Dynamics of large-scale magnetic inhomogeneities in seignette-magnetics with linear magnetoelectric effect
The nonlinear dynamics of 180° domain walls in magnetics with linear magnetoelectric interaction is investigated. The features of oscillatory and drift motion of domains in variable magnetic and electric fields are discussed. The drift velocities of ac- and ab-types domain walls as functions of the frequency and phase shift of external fields are obtained. It is found that the velocities can reach several tens cm/s for resonance frequencies.
