High-frequency energy absorption by a solitons gas in one-dimensional magnet

Abstract:
The additional mechanism of the super-high-frequency power absorption in the quasy-one-dimensional antiferromagnet with the propery of high symmetry was considered. This absorption works due to the generation of the stationary nonlinear excitations of kinks type. The shape of the signal of absorption is analyzed for some values of the external magnetic field.
