Abstract

Specific features of the dynamics of magnetic domain walls of a two-sublattice ferrimagnet with two compensation points: angular momentum compensation temperature ТА and the magnetization compensation temperature ТМ, are studied. Based on the effective Lagrangian method, Slonczewski-type equations of the dynamics of domain walls in the region of ТА are obtained. The stationary and nonstationary dynamics of domain walls in ferrimagnets are calculated in the presence of combined “easy-axis” and “easy-plane” anisotropy. It is shown that the “easy-plane” magnetic anisotropy field leads to a shift in the Walker field and a change in the characteristics of the unsteady motion of domain walls.
