Abstract

The magneto-optical method is used to study the dynamics of the oscillatory motion of domain boundaries in a Tb3Fe5O12 garnet ferrite in the temperature range 200-295K, including the magnetic compensation point of this ferrimagnet Fs ≈ 249K. To interpret the experimental results obtained, a theoretical model of magnetic resonance of domain boundaries is proposed, according to which when the temperature approaches the compensation point, the mass of the domain boundaries tends to infinity, and the resonance frequency tends to zero.
