Specific features of magnetic hysteresis in single-crystalline uniaxial M-type hexaferrites

Аннотация

The effect of magnetic hysteresis in M-type hexaferrite single crystals has been studied experimentally. Earlier experimental data for the special aspects of the magnetic spectrum hysteresis, the parameters of which differ considerably from those of well-studied classical hysteresis, have been discussed. It has been shown that, after the nucleation of oppositely magnetized domains, the domain walls do not shift until the external magnetic field acquires a certain value.
