摘要: The nonlinear phase shift and damping of spin-electromagnetic waves were theoretically studied for the first time in sub-terahertz frequency range infinite homogeneous longitudinal magnetized multiferroics. research was based on solution Ginzburg-Landau equation. It is shown that saturation occurs due to if coefficients exceed v1=108 s-1 v2=109 s-1.
