  The spin effects on electromagnetic waves in a strongly magnetized plasma
with rare collisions is considered with the help of relativistic kinetic
equations, which takes into account the electron spin dynamics in the
selfconsistent electric and magnetic fields. It is shown that for
electromagnetic waves propagating almost perpendicular to ambient magnetic
field the spin effects become essential in the vicinity of electron
gyrofrequency and the corresponding wave dispersion and growth rate of the
electromagnetic spin waves in the presence of intense quasi monoenergetic
fluxes of neutrino is determined.
