The effect produced by screening the electric field of ions is treated as a result of the zero plasma OBOillationsAf the electr~, gas (which are analogous to the optical oscillations in ion crystals). The screening constant k0 of the Coulomb field is at first estimated~ and an approximate expression for the velocity of sound in ion crystals is found. Formula (3) gives the Hamiltonian H of the system of interacting ions; in the latter the chaotic ion motion and its influence upon collective vibrations may be neglected. The operators for the production and annihilation of phonons (4) are defined and introduced into H.

Calculations aremade for both-quadratic (but.anisotropic)-1 and arbitrary dispersion laws, and it is shown that for'the latter case an experimental investigation of the magnetic susceptibility will.yield the field dependence of the energy and of the state denwity at the ground state; in the case of a quadratic dispersion lav., in strong magnetic fields, the total magnetic moment (diamag- netic and paramagnetic) tends to saturation. The monotonic part of the susceptibility is obtained by subtracting the oscillating part (the deHaas--VanAlphen.effect). Itis concluded that in strong,magnetic fields the magnetic rroment in the main approximation does not depend on the temperature and is determined-only by the magnetic-field-dependence of the ground state energy. In extremely. strong magnetic fields, the magnetic moment is subject to a small increment that depends linearly on the temperature; the proportion--- ality coefficient is determined by the density of states at the ground state.

In 38 children the mud therapy was given in the subacute phase. Usually after the first 2 or 3 treatments the pain in the limbs diminished or even disappeared and recovery of movement took place in paralysed muscles. This re- covery of function was irregular. Recovery was delayed longest in m. m. quadri- ceps. peroneus brevis, peroneus longur and deltoid. It took up to I or 2 yr. The course of mud therapy comprised from 15 to 30 treatments. All the children to- lerated them well. The children were kept under observation after discharge from the unit and long-term domiciliary treatment was arranged - massage, exercises and orthopaedic measures. One month after discharge diathermy was given; sun baths were also provided; after 3 months a course of dibazol; after 5 months a course of galvanism and ultra-violet irradiation. The mud treatment was repeated after one year or sometimes ELfter 6 months. The full course of treatment extend- ed over 3-4 yr.

The influence of paramagnetic re- sonance on the opticalooffect is based upon spin-orbit inter- actions. The dielectric constant characterizes the optical properties, and as the otate of the spin system varies con- siderably within ran-e of paramagnetic resonance, a change of the state of the spin system (in consideration of spin- orbit coupling.) leads to a variation of the dielectric con- stant, which fact explains the influence exercised upon opti-- cal properties.

Electrical Cond!!ctivitzAf Ferromagnetic Metalsilln a Radio-Frequcney Field PERIODICAL: Fizika metallov i metallovedeniye, 1959, vol 8, Nr 6, pp 8ol-8o6 (USSR) ABSTRACT: It is well known that ferromagnetic metals have an additional resistivity due 'to the interaction of conduction electrons with thermal fluctuations in the magnetization. In the case of ferromagnetic resonance, the character of the magnetization fluctuations may be altered quite considerably. The resistivity of a metallic ferromagnetic may be looked upon as consisting of three components, namely those due to the interaction of the conduction electrons with phonons and ferromagnons, and a further component due to the change in the magnetization in a radio frequency field. The temperature dependence and the order of magnitude of the first of the above three components is well known. The second component has been calculated by Turov (Ref 1) for the low temperature region, using the spin wave niodel; the Card 1/3 temperature dependence of this component is in a 67655 SOV/126-8-6-1/24 Electrical Conductivity of Ferromagnet�c Metals in a Radio-Frequency Field qualitative agreement with experiment. The present authors attempt to set up a quantitative theory of the increase in the resistivity of ferromagnetics in a radio-frequency field. Near the ferromagnetic resonances the energy of the radio-frequency field is transferred to s[jin waves having a wave number close to zero and this corresponds to an increase in the precession angle,of'-the magnetization vector. Since in this case the magnetization remains uniform, there is no additional contribution to resistivity. However, in the case of a ferromagnetic metal in a radio-frequency field, the magnetization in the skin-layer x~ill no longer be uniform and the radio-frequency field will tend to increase this nonuniformity and excite a spin wave with a'wave number k,.v,l/6, where 16 is the depth of the skin-layer. This increase in thenonuniformity of the magnetization in the skin-layer near resonance will give rise to an additional interaction of conduction electrons with the metal and hence the resistance of the skin-layer has a resonance Card 2/3 character. The effect can be observed in thin films 3) .1 0 AUTHORS; Skrotskiy, G. V,, Kokin, A.

TITLE: The Theory of Paramagnetic Resonance in Systems Containing Two Kinds of Magnetic Moments PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959, Vol 37, Nr 2(8), PP 462-489 (USSR) ABSTRACT: The authors develop a better and more complete (escompared to that of G. V. Skrotskiy, Ref 4) thermodynamical and micro- scopical theory of systems containing two kinds of magnetic moments. This theory is developed for weak alt6rnating fields, includ4ng the..,.deduction of equations,for the partial magnetiza- tions 1 and M 2* The thermodynamical theory of the systems under consideration can be developed.on the basis of the thermodynamics of irreversible processes. The paramagnetic sample is considered to be in a constant mtgnetic field H=H and in an alternating magnetic field (t), which is a slight disturbance to the thezmodynamical equilibrium. In this case the partial magnetiza-w-;.ons M.=11.(t) (j=192) of the a j k), subsystems satisfy the equations IM 1j - ~-_ Llm' jk(h MW - h m m9k 1,m~ x,y,z; j,k = 1;2, which are 1-inear with respeetto the Card 1/3 variable field.

The variation of the temperature of the subsystems is ignoredp and is arbitrarily assumed to be equal to the temperature of the sample. The free precession of the magnetization *~ t)vO in the constant magnetic field Ito is investigated. In the sequel the solutions of the above linear equations of motion for the partial magnetizations are determined and written down. The microscopical theory of the relaxation and resonance pheno- mena in systems with two kinds of magnetic moments can be devel oped on the basis of the method due to R. Kubo and K. Tomita (Ref 6) in a manner similar to that employed by the authors for the case of one kind of spin (Ref 7). The g-factors Card 2/3 of the particles are assumed to be isotropic. By a suitable SOV/56-37-2-23/56 The Theory of Paramagnetic Resonance in Systems Containing Two Kinds of Magnetic Moments choice of the Hamiltonian it is possible to account for the quadrupole moments of the nuc1eA_,_.&toma._and_,_1ons and their intera-~,tion with the local inhomogan-p-oun-and generally fluc- tuating electric field. Moreover, it is.pQasible by these means to account for the weak direct-and indirect exchange interactions (which lead to a hyperfine.structure). The relaxa- tion functions are determined for a homogeneous and isotropic medium. The relaxation time and the displaaement of the resonance frequency of one subsystem are intexmlated -with the relaxation time and the resonance frequency of the.other subsystem. This means that a general relationship exista.analogous to that of Kramers-Kronig. The real and imaginary part of the suscepti- bility are interrelated through these relations.There are 9 references, 5 of which are Soviet.

TITLE: On the Influence of the Coherent Magnetic Dipole Radiation on Magnetic Resonance PERIODICAL; Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959, vol 37, Nr 3(9), pp 802-804 (USSR) ABSTRACT: L. I. h1andel'shtam (Ref 3) was the first to find out that coherence phenomena occur during the emission of electromag- netic quanta caused by a spin system, if the wavelength is greater than the dimensions of the system; these phenomena lead to a considerable increase of the radiation width of the line (cf. also Refs 1,2,4). V. M. Fayn (Ref 5) found that taking spin interaction into account by means of a general radiation field in the radio frequency range leads to a shift of resonance frequency. In the present paper the authors calculate the corrections to the relaxation time and calculate the additional resonance frequency shift caused by the coherent radiation field. As expected, the quantum theory, within the approximation investigated, leads to the same results as the ,,-t.vd 1/4 classical one. The classical equation of motion for a magnetic SOY/56-37-3-32/62 On the Influence of the Coherent Magnetic Dipole Radiation on Magnetic Resonance moment ~k of a homogeneously magnetized sample that is small compared to the wave length of the radiation, is set up ac- ) as follo _ 4YL)m [~LC] + cording to Ginzburg (Ref 6 WS: y[ttH'j 31tv3 L 2 3V5 V = CIVEt( is the phase velocity of light in sample matter, and W.~Z~ cv-1/3.

The method developed in Ref. 1 for the determination of the refractive index of non-conducting paramagnetic media in the presence of a radio-frequency field is. In fhe present work, extended to coaducting ferromagnetic substances. This enable8 one to make an estimate of the effect of ferromagneti-6 resonance on the magnitude of the magneto-optical Kerr effect.

Spin Resonance on Conduction Electrons in FerromMnetic Metals V PERIODICAL: Fizika tverdogo tela, 1960, Vol. 2, No. 8, pp. 1766-1772 TEXT: The spin resonance of conduction electrons in alkali metals has been already investigated both theoretically and experimentally. It is found that the diffusion of conduction electrons in the skin layer leads to a strong asymmetry of the absorption lines. For very fine metallic particles, which are smaller in size than the thickness of the skin, the symmetry of the absorption lines is retained. In this case the line- width amounts to some ten oersteds and depends linearly on temperature, and tends to a definite value for T-),OOK. It was shown that for alkali metals the resonance takes place at the Larmor frequency. Now, the problem the authors posed for themselves was to investigate the conditions for the resonance absorption on conduction electrons in ferromagnetic metals. Since in this case there exists a spontaneous Card 1/3 82993 Spin Resonance on Conduction Electrons S/181/60/002/008/012/045 in Ferromagnetic Metals B006/BO70 magnetic moment, the energy of the conduction electrons must depend on the orientation of the spin relative to the magnetization vector, and for the simplest case it may be assumed that the energy of an electron E6' 4s a function of both the quantum numbers ~ and 0' (quasimomentum t - and spin). The form of the magnetic resonance absirption lines is calculated on the assumption that the effective mass of conduction electrons depends on the orientation of the spin relative to the spontaneous magnetic moment.

The effect of magnetic-field inhomogeneities on the amplitude of free precession is examined. It is sho,4m that in the case of a constant gradient and a cylindri- cal specimen, the envelope of the oscillations of the free-preceSsion signal can be expressed by a Bessel function of 'the first order, which corresponds to the appearance of well pronounced beats. Calculation results were substantiated experimentally. Card 1/g/ Rr.,HKOV, V.M.1 SKROTSKIY, G.V. ~ . - .....0 Uses of free precession methods. Trudy Ural. politekh. inst. no.3-11:63-70 t61.

'no.8. 1961. 36-65 TEXT: The special features of mag~netometers based on free nucmeax- precession are discussed. The frequency offree precession is strictly proportional to the total'vector magnetic field strength, and so field strength can-be assessed absolutely and not as an increment over an unknown lovel as in permalloy magnetometers. Given adequate signal-to-noise ratio, the accuracy, depends on the accuracy with ~fhich the proton magneto/mechanical ratio Yp Is known-far water or other-fluid, and.the measurements Of this is discussed. Accuracy can be,.improved by increasing the magneto/inechanical ratio, the duratibn of.measurements, the signal-to-noise ratio, or the strength ofthe magnetic field being measured. Similar considerations alsoapply to resonance methods Card 1/.$ Radio-spectroscopic methods of 5/785/61/000/008/001/005 E194/E155 of measurement. Ways of reducing inaccuracies due to atmospheric and industrial noise are briefly explained. Frequency is usually measured by counting the cycles of free precession in a fixed time interval. With one-second interval, the accuracy required is- 0.04 c/5. After describing methods of frequency measurement, existing precession magnetometers are reviewed in three groups according to method of frequency measurement. In some magneto- meters the beat signal and standard frequency are recorded together with time markers; others use vibration frequency meters. However, the most widely used is the third group employing electron counter frequency meters. A novel Soviet portable instrument is described and so are the instruments used in the Vanguard satellites. The foregoing relates to measuriament of the modulus of the magnetic field vector. By combining the magnetometer and Helmholz rings the direction of the vector in three-dimensional space can also be measured; various methods are expla 'ined. The free-precession method can also be used 'to measure magnetic field gradients. Despite their-considerable advantages, 'free-precession magnetometers have certain disadvantages--, particularly the small Card 2/~~-/ Radio-spectroscopic metho'dm of ... S/785/61/ooo/oO/ool/005 E194/EI55 amplitude of the output signals. This necessitates the use of large pick-ups and powerful polarising sources. The sample must be reinagnetised from time to time, which interrupts operation and prevent.s the use of simple methods of.frequ4pney measurement and limits the speed of the measurement.0 Because of the low frequency of precession in the terrestrial magnetic fields, measurem'ent times are unduly long. Accordingly, possible developments in radio spectroscopic magnetometers for weak fi6ld measurements are discussed. Magnetometers using the Oberhauser effect have been suggested, but would require a suitable paramagnetic salt which, when dissolved in a liquid containing protons, would give greater signal strength without appreciably altering the relaxation time* Oberhauser-effect magnetometers are more intricate than free- precession magnetometers because they use complicated high-frequency generators. Nuclear-preCeS5ion generators (with Maser-type feed- back and flowing liquid) can provide a continuous undamped precessional signal, whose frequency follows the magnetic field intensity, but they cannot make continuous measurements. Magnetometers may be characterised by their ability to record actual Card 3/~i~ Radio-spectroscopic methods of S/785/61/000/008/001/005 E194/E155 magnetic anomalies. Precession aeromagnetonie'ter type A 311-49 (AEm-49) can record at a rate of 80 y/sec and anomalies which vary as fast as 200 y/sec are recorded with considerable error. The speed of measurement of nuclear generators may be increased by .using several frequency-meters operating,dt successive time shifts. Nuclear-precession magnetometers determine the total field strength at each measurement and the field change'between measurt-nents does. not exceed 0.10,0'. They thus 'give excess information which could in principle be used to ensure greater speed and accuracy. Their frequency meters may be more simple and interference-free than the electron-counter type, but are less stable than those used in the free precession method. Electron resonance and free precession might be used in magnetometers, and work in this field is briefly reviewed.

TITLE: Theory of double electron and nuclear resonance in systems with hyperfine interaction PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, v. 40 no. 1 , 1961 , 133-142 TEXT: The method of double maGnetic resonance is applied to systems con- taining two kinds of magnetic moments; here the specimen is exposed to a constant magnetic field and two. variable magnetic fields, whose tequencies are near the Larmor frequencies of the precession of the two types of mag- netic moment. In interactions of the latter (e.g., hyperfine interaction) a correspondence of resonances of two systems occurs. In the presence of nuclear and electronic paramagnetism, the hyperfine interaction leads to a number of effects, which may be subdivided into two groups. The first group comprises effects due to the action of electron paramagnetic resonaice upon nuclear resonance (e.g., Overhauser effect). The second comprises effects that are due to the action of nuclear resonance upon electron resonance. Card 1/4 89208 S/056/61/040/001/014/037 Theory of double electron ... B102/3204 Such an effect was observed for the first time by Feher and was qualitative- ly explained. (The saturation of the nuclear system leads to no noticeable polarization of the electron spins, whereby the conditions for the satura- tion of the electron system are changed and a change in the absorption of the energy of an r.f. field is caused by the electron system). The present paper gives a quantum-mechanical analysis of the effect produced by nuclear magnetic resonance upon paramagnetic resonance. Such an analysis cannot be carried out within the framework of the linear theory of magnetic resonance. The authors operate by means of the method of the statistical perturbation theory developed by Tomita.4 A system is studied which consists of non- compensaled electron spins sk, which are near several nuclei with different moments Il. Between electrons and nuclei a scalar interaction is a,,sumed, and also an interaction between electrons and lattice. The magnetic field in which the specimen is located, is assumed to be characterized by + H = H0+ hS(t) + hI(t), where h and h I are the strengths of the microwave and the r.f. fields. These fields e~ assumed to be circularly polarized in a plane that is perpendicular to .

Mis further assumed that the energy of hyperfine interaction is low compared to the Zeeman energy of the electrons, in which case electron and nuclear spins preaess independently around the strong constant field Ho, and the hyperfine interaction may be considered as a perturbation. In this case, the hy'perfine interaction leads to.an irregu lar broadening of the epr lines (Ref. 6), which, as the spin system is not in equilibrium, is also a function of time. On these assumptions, the equation of motion for the magnetization vector of the electron.system is determined which, in first approximation (taking account of the terms linear inh.Q./kT) reads 'as follows: Card 316 W-08--.7 S/056/61/040/001/014/037 Theory of dbuble electron B102/B204 d- r ~:j 7t- < Nr r ILV,.

The Soviet receivers have superhet functions, are equipped with an additional oscill- lator for fm reception and use 2 frequency-mixing stages. Upon the first mixing, an intermediate frequency arises which is conform to the interme- diate video frequency, a,-,d upon the second mixing, a frequency of 6.5 mc is resulting, conform to the original intermediate audio frequency. This stage Card 1/2 is tuned with the same elements as used for TV CZECH/14-60-3-8/56 Reception of FM Broadcasting With a TV Receiver tuning. The receivers are fed from 2 transformers and the one, supplying the video circuits is dis- connected during fm radio reception. The oscilla- tor frequency is fed to the demodulating diode either directly or thru the last stage of the inter- mediate video-frequency amplifier. Mixing takes place due to the non-linear characteristics of the V/ diode and a frequei--cy of 6.5 me results, same as in TV reception. The audio stage, tuned to this fre- quency, processes the fm signais the conventional way up to the loudspeaker. The author gives then a wiring diagram of the Czechoslovak TV receiver "Athos" modified for fm radio reception (graph 3). % There are 3 diaGrams.
