Essay

For the first time the wave-front reversal (WFR) of dipole-exchange spin waves (DESW) in the yttrium-iron garnet (YIG) films has been obtained by method of parametrical interaction DESW with electromagnetic pumping. The conditions of the optimal efficiency have been founded. The two-magnon scattering of magnetostatic waves was used for excitation DESW. The influence of inserting inhomogeneities has been studied and increasing of reversed signal DESW has been achieved. The multiple WFR for DESW has been obtained.
