The effect of Cu substitution on the electrical and magnetic properties of NiZn ferrites

The effects of Cu substitution on the properties of NiZn ferrites sintered at low temperature with various compositions are investigated. The densification of NiCuZn ferrite is dependent upon Cu content in the composition, (Ni/sub 0.5-x/Cu/sub x/Zn/sub 0.5/)(Fe/sub 2/O/sub 3/)/sub 0.98/. Dispersion...

Zusammenfassung:The effects of Cu substitution on the properties of NiZn ferrites sintered at low temperature with various compositions are investigated. The densification of NiCuZn ferrite is dependent upon Cu content in the composition, (Ni/sub 0.5-x/Cu/sub x/Zn/sub 0.5/)(Fe/sub 2/O/sub 3/)/sub 0.98/. Dispersion characteristics of complex permeability of (Ni/sub 0.5-x/Cu/sub x/Zn/sub 0.5/)(Fe/sub 2/O/sub 3/)/sub 0.98/ is observed above x=0.3 and the relaxation frequency increases with higher temperature.
