    • Abstract


      The time dependent magnetization measurements of the fine particles (100Å) of Zn0.1Fe0.9Fe2O4 ferrite system at 68 K are reported. The time decay of magnetization is found to be logarithmic. The time dependent co-efficient varies with the applied field and is maximum at coercive field. The value of anisotropy obtained from the variation of time dependent co-efficient with field agrees well with earlier results.
