Abstract

The effect of a strong magnetic field H, perpendicular to the easy axis of a ferromagnetic, on the motion of a domain wall is investigated. It is shown that the peak velocity of motion vc is defined by various scenarios at weak (H≪Ha) and strong (Ha - H ≪ Ha) magnetic fields, where Ha is the anisotropy field. Therefore, the peak velocity Vc is a non- monotonous function of the magnetic field, when H ranges from 0 to Ha. The character of the DW velocity dependence on the driving field Hz was studied.

Abstract

The interaction between a ferromagnetic monolayer and nonmagnetic substrate is investigated. The characteristic dimension of superstructure arising in a film is estimated. New types of surface magnetoelastic waves are obtained near the 2D phase transition of a homogeneous magnetic state to the state with surface superstructure.
