Influence of Conductivity Frequency Dispersion on Mirror Spectral Crossover in Magnetized Conductor

Within the Faraday’s geometry, conditions of existence of a new type of spin-wave resonance in a magnetized conductor - metal or semiconductor - are obtained. They correspond to a mirror intersection of real parts of complex wave vectors - mirror spectral crossover. Equations are derived for determining conditions of existence of the mirror spectral crossover on a plane frequency - strength of the constant magnetic field, applied to a conductor. The conditions depend: strongly -on the Hall’s constants, the magnetic relaxation constant and the relaxation time of carriers of the current; weakly - on the non-uniform exchange constant.
