Evolution of the Hysteresis Loops of Iron Garnet Films upon Deep Layered Etching

Аннотация

Dependences are studied for the parameters of the hysteresis loops of iron garnet monocrystalline films on film thickness as a result of their layered etching by ion-beam sputtering with an oxygen ion beam. The coercive force of the films in magnetic fields corresponding to the motion of domain walls does not exceed 0.6 Oe as a result of layered etching through as much as 90% of a film’s thickness. This is important when using films in devices based on domain walls and other nanoscale spin structures.
