Structural and Magnetic Characterizations of Nano Structured Ni 0 . 8 Zn 0 . 2 Fe 2 O 4 Prepared By Self Combustion Method Majid

1928091 IJBAS-IJENS @ International Journals of Engineering and Sciences IJENS Abstract— NiZn ferrite with composition Ni0.8Zn0.2Fe2O4 was prepared by the self combustion technique. The samples were sintered at 750 °C and 950 °C and characterized by XRD, SEM and Raman spectroscopy. From the analysis of X-ray diffraction patterns, the single phase and good nanocrystalline of Ni0.8Zn0.2Fe2O4 particles were obtained at sintering temperature of 950 °C. The particle size ranges from 25 to 36 nm was observed by XRD and SEM. Raman results show the confirmation of spinel structure. It was found that grain size increases as the sintering temperature increased from 750 °C to 950 °C. The cubical shape microstructure of Ni0.8Zn0.2Fe2O4 was observed at sintered temperature of 950 °C. The ferrite powder was also characterized for permeability, relative loss factor and Q-factor. The initial permeability was found to increase and relative loss factor decreased at high frequency. The powder sintered at 950 °C can be used for high frequency application and multilayer chip inductor due to low temperature sinter ability and low loss at high frequency.
