Abstract
This work is devoted to the investigation into the effect of surface magnetic anisotropy on the motion of domain walls in magnetic uniaxial films with an in-plane anisotropy in the range of thicknesses corresponding to the stability of one-dimensional Neel walls. It has been established that the surface anisotropy with a constant K s > 0 (K s < 0) increases (decreases) the velocity of both stationary and nonstationary motion of the domain wall, as well as the period of oscillations of the velocity of nonstationary motion. The magnitude of the critical field as a function of K s has been determined. Effect of surface anisotropy with K s < 0 on the scenario of the dynamic transformation of the domain-wall structure has been revealed.
