Abstract
Selected magnetic properties of (Ni0.33Zn0.67)1+xFe2-xO4 ferrite (where x = 0; 0.08; 0.12; 0.2) are investigated. The Curie temperature and the maximum flux density of Ni0.33Zn0.67 ferrites with Fe deficiency increases due to the increase in super-exchange interactions between A-B sites of spinel structure. Deficiency of Fe results in a decrease of grain size, susceptibility and permeability, meanwhile the coercivity and resonant frequency increase. The physical characteristics of the resulting products were investigated by X-ray diffraction, Mössbauer spectroscopy and thermomagnetic analysis. Deficiency of Fe in the studied composition extends temperature scale of the ferrite applicability, as well as enhances a temperature stability of ferrite. [ABSTRACT FROM AUTHOR]
