Abstract

The dependence of the domain-wall velocity V on the acting magnetic field H is investigated for (Bi,Yb)3(Fe,Ga)5O12 garnet ferrite single-crystal films in the vicinity of the angular momentum compensation point at different temperatures. The films are grown by liquid-phase epitaxy from a supercooled solution melt on Cd3Ga5O12 substrates with the (111) orientation. It is demonstrated that, in these films, the precessional mechanism is not responsible for the motion of domain walls but there arises an internal effective magnetic field that weakens the acting magnetic field.
