Abstract
The temperature dependence of the anomalous shapes of the Mössbauer spectra of Ni0.25Zn0.75Fe2O4 in presence of an external transverse field of 12.3 kG has been studied. It is found that the anomalous dependence of < Sz > of Fe3+ ions on temperature, noted in an earlier investigation, is partly removed in the presence of this field. The temperature dependence of the ionic spin relaxation time, in the presence of the external field is similar to the behaviour found earlier without the external fieldKeywords
