TITLE: The Theory of Spin Waves~
PERIODICAL: Fizika tverdogo telaq 1960, Vol. 2, No- 5, PP- 913 - 921
TEXT: The present paper was read at the Seminar of the Theoretical
Department of FIAN on January 7, 1959. The basic relation in the theory
of spin waves re-,as known, the dispersion law - the dependence of the
wavelength X on frequency * Hitherto, the theory of spin wav*8 had been
based upon a dispersion law (Refs. 1-3) which is mathematically ex-
pressed by equation (1). On. the basis of the statements made in the
paper, the question arises as to the manner in which transition from
spin waves to electromagnetic wavemi0takes plaoe, as to the nature of
the waves in the transition zone, and as to the part played by absorp-
tion. This question is briofly dealt with by the present paper. In case
A a lose-free ferromagnetic is studied. At 9 - 0 the dispersion law
eq ation (2)) takes the form of (4). With an increase of frequency in
4)uq this equation continuously goes over into equation (1) (see Fig.1

In Fig. I the solid curves represent the dispersion law (4) and the
analogous relation for 0 - %/2, whereas the broken curves illustrate
the dispersion law (1). The next paragraph deals with the case of real
ferromagnetics. Fig. 2 shows the curves k,(&)) and k 2((~)) for both
branches of equations (8) and (9) (solid curves), whereas the broken
curves illustrate the dispersion law (1), where k, is the wave number,
and the imaginary part k2 is the damping coefficient (k in equation (9)
is complex: k - k1 -1k 2) . A further paragraph deals with the dispersion
law of spin waves for an arbitrary direction of their propagation. The
position of the branches of the dispersion curves for this case is
given in Fig. 3. There are 3 figures and 15 references: 3 Soviet,
2 German, and 10 British.

TEXT: A stream of particles moving in a plasma in the
direction of an external magnetic field can radiate transverse
electromagnetic waves. This can be applied-to the ca8e of
ions and electrons from the Sun moving in the ionized atmospacre
of the Earth. A Maxwellian velocity distribution is assumed
in the stream (with a small correction due to the pr4sence of
,
a
field). (All terins in the equations are used to a ~Cirst-
order approximation.) An expression is then derived for the
effective electrical conductivity . The problem is restricted
to trying to find a value for the wave number which will)
correspond to instubility of the 'solar corpuscular stream, in
the Earth's exosphere - this being the condition for radio
waves to be emitted. In practice this means that one looks

electrons. Fig. I shows the dependence of v (Curve A) and
u!2 (Curve B) on frequency. v- has a inaxi.Lmum at 1/2W
(where W H is the Larmor frequency for the electrons).
U2 has a minimum value at w = 2.7 1Z H , at which point
it is equal to 2.6 v- (where v. is the phase velocity
of hydromagnetic waves). Ion streams with velocities greater
than u 2,min therefore excite an extraordinary wave in the
plasma. The electron stream excites waves of opposite
polarization. The dispersion of' these, however, is determined
by the ions. In order to excite the waves it is necessary that
the increment (the imaginary part of the angular frequency)
due to the corpuscular stream should be greater than the
decrement (that is, the damping due to collisions and
cyclotron resonance absorption). The author next considers
typical conditions in the Earth's exosphere, at a distance
of 28 x 103 kin from the centre of the Earth (Ref. 4). lt is

shown that the velocity of solar corpuscular streams is fast
enough to excite waves. For a stream velocity of
8.5 x 108 cm see-1 , three ranges of frequency are excited:
- 5 c-P-s-s 850 c-P-5. and 7 6oo c.p.s. The low-frequency
range is probably connected with micro-pulsations of the
Earth's magnetic field. Assuming an average stream velocity
of 2 x 108 cmsec- 1, the requirements for instability are
satisfied in the ionosphere jh < 700 km) and in the outer
radiation belt (h > 2.5 x 10 km). observations of low-
frequency radio waves from corpuscular streams by R. Gallet,
R. Helliwell and G. Ellis (Refs. 6-8) agree well with the
predictions of this paper. Eq. (5) also demonstrates the
predicted correlation between the radio waves and magnetic
activity. The author estimates the amplitude of the excited
geomagnetic pulsations to be about 10 - 100 y

Thus, the protons of the solar corpuscular stream can excite
electron plasma waves in the exosphere, the frequency being close
to the proper frequency for electrons in the plasma f 0--N- 300 kc/s,
Measurement of the frequencies of these waves would provide
information on the parameters and nature of corpuscular streams.
Plasma waves will be propagated only at frequencies close to f
Since f 0 is proportional to the concentration N and the
latter increases towards the Earth's surface, it follows that plas,al
waves which originate at large altitudes cannot penetrate towards
the Earth's surface. However, plasma waves (without a magnetic
field) can become transformed into electromagnetic waves on
scattering and can reach the Earth's surface in this form. it
follows that, in addition to polar auroras and magnetic variations,

solar corpuscular streanig should produce radio noise in the
frequency range 105 - 10 cps on the Earth's surface. Dowden (Ref.9)
has reported radio noise of exospheric origin on 230 kc/s and the
present author identifies this with the above waves. Owing to the
screening effect of the ionosphere, this noise is best observed
from a rocket or a satellite. Plasma waves can also be excited by
beams under laboratory conditions. In recent years considerable
effort has been devoted to possibilities of ion jet propulsion.
The ion beams producedin these experiments may also generate plasma
waves. A graphical method is described which can be used to
estimate the stability of the ion beam under these conditions.

TEXT: The radiation from a single ion in the solar corpuscular
stream (SCS) interacting with the earth's magnetic field is con_
sidered. Apart from radio frequencies, solutions are found for low-
frequency mhd-waves in the range 0.1 to 0.001 c/s and it is sug-
gested that these are components of the earth's ahort-period va-
riation field. It is shown in the course of the theory that the
ion must be travelling at super-critical speed (i.e. with a velo-
city greater than that of radiation in the plasma) in order to ra-
diate in this mode. The cases are divided into two, according as
u, the velocity of the ion, is greater or less than the velocity
VA of radiation in the plasma. For the subcritical case, the ex-

discussed of the focussing effect of the field which brings the
group-velocity vector closer to the field-line direction than the
wave-vector. The attenuation and polarization of the low-frequen.,--y
waves are also discussed. It is concluded that a sin-le ion with
suberitical velocity travelling along the field cannot radiateo
(i.e. there is no incoherent radiation with u< v A). Coherent ra-
diation also disappears. However, the position is radically diffe.-
rent for ions travelling with super-critical velocities, where both
coherent and incoherent radiation at very low frequencies in an
mhd-mode are possible for all directions of the ion relative -to the
field. There is a mathematical appendix. There are 1 figure, I
