| Zusammenfassung | The mean domain size and the preferred orientation of the domain magnetization were observed in Ba-ferrite glass ceramics containing 22 volume% BaFe12O19 during magnetization reversal along the remanent and the demagnetizing branch. Except for the virgin state, the mean domain size, as measured by the magnetic correlation length, exceeds the mean particle size considerably. The maximum during the magnetization reversal attains 1 μm compared to 240 nm in the virgin state. This fact and the preferred orientation of the domain magnetization indicates that strong correlations are introduced between the Ba-ferrite particles during the magnetization process. |
