NONLINEAR-WAVES OF MAGNETIZATION IN IRON BORATE

A new type of magnetoelastic waves in an easy-plane ferromagnetic with the transverse corrugation type of self-organization of a structure whose period depends on the external magnetic field, has been observed and magneto-optically visualized. The dynamics of the domain wall in iron borate and its behavior in the magnetic and intense sound wave field have been studied. The possibility of a dynamic orientational transition under both magnetic and sound field with the destruction of the domain wall upon reaching the critical velocity depending on the external pressure has been shown.
