Abstract

The transverse susceptibility was measured in polycrystalline soft ferrimagnetic ring samples. It is shown that the very peculiar shape of the transverse susceptibility curve comes form the combination of two magnetization processes: the 180° domain-wall motions which give rise to the initial susceptibility, and the sudden rotation of domains magnetized perpendicular to the applied field when a certain threshold of the biasing field is reached. The temperature dependence of this threshold has been investigated and has shown a close connection with the effective anisotropy field
