Abstract
Disordered spinel ferrites exhibit relaxation behaviour in their Mossbauer spectra. The results of the low-field magnetisation measurements on a representative system show for the first time that the system undergoes a ferrimagnetic transition at TN and then, on cooling, enters into a cluster spin-glass state below Tf with the magnetisation of different clusters randomly frozen. The observed relaxation features in the Mossbauer spectra could be related to the instability in the ferrimagnetic state at higher temperatures.Keywords
