Spin waves in paramagnetic metals

The excitation of spin waves in paramagnetic metals by circularly-polarized electromagnetic waves is considered. An investigation is made of the effect of boundary conditions for the magnetic moment on the amplitude of the electromagnetic-spin waves in a metal. The same investigation is carried out for the surface impedance.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 7–10, January, 1974.The author acknowledges A. Ya.
