Investigation of structural and magnetic properties of Sn-substituted NiZn spinel ferrites

In this paper, Sn-replaced Ni0.6Zn0.4SnxFe2-xO4 (x = 0 similar to 0.2) ferrites were prepared by solid-phase reaction method and their properties were studied. It is beneficial to characterize the crystal structure by X-ray diffraction, and the microstructure of the sample can be observed by scanning electron microscope. The magnetic energy of the sample is measured using the BH analyzer. The experimental results show that the substitution of Sn is not to change the phase and microstructure of ferrite, but the valence state of the metal ion is adjusted. In addition, Sn substitution effectively reduces the eddy current loss of the sample. When x = 0.05, the eddy loss of the sample decreased by 31%.
