Classical Dependence of the Domain Wall Velocity on the Magnetic Field in Garnet Ferrite Films with Orthorhombic Magnetic Anisotropy

摘要

The dependence of the domain wall velocity V on the acting magnetic field H is investigated for bismuth-containing single-crystal garnet ferrite films with orthorhombic magnetic anisotropy. It is shown that this dependence includes both the initial linear portion and a saturation portion and exhibits a complex behavior. This behavior is explained within the model of domain wall motion with spin wave radiation.
