ABSTRACT: Ni-Zn ferrite materials were prepared by traditional ceramic preparation technology .SEM and XRD were used to observe the microstructure and the magnetic properties was tested by Agilent 4294A impedance analyzer . The influence of sintering temperature on the initial permeability, power loss and microstructure of the Ni0.4Zn0.6Fe2O4 ferrite materials was investigated. When sintered at 1250℃, Ni-Zn ferrites possess better overall performance, high magnetic permeability and low loss.
KEY WORDS: Ni-Zn ferrite; sintering temperature; initial permeability; power loss
