Abstract :
The Fe3O4 powder were mixed with Cu-ferrite powder in different amounts (0∼30 mol%). The mixed powder was compressed and then sintered at various temperatures. The effects of sintering temperature (Ts) on the microstructure and magnetoresistance ratio of the sintered ferrite were investigated through SEM and XRD.
