Drift of domain walls in a harmonic magnetic field

Drift of domain walls in a harmonic magnetic field

It is shown that a two-step form of the dynamic magnetization curve (and the hysteresis loop) established for a multiaxial ferrite-garnet wafer with a low quality factor ( Q < 1) and considerable anisotropy in the plane ( K p / K u = 14) in the frequency range of 25–1000 Hz is explained by the re...

Zusammenfassung:It is shown that a two-step form of the dynamic magnetization curve (and the hysteresis loop) established for a multiaxial ferrite-garnet wafer with a low quality factor ( Q < 1) and considerable anisotropy in the plane ( K p / K u = 14) in the frequency range of 25–1000 Hz is explained by the reconstruction of the dynamic domain structure, particularly by the established features of the drift of domain boundaries in the harmonic magnetic field.
