Impact of V substitution on the physical properties of Ni–Zn–Co ferrites: structural, magnetic, dielectric and electrical properties

Abstract We have investigated the Vanadium- (V) substituted Ni–Zn–Co ferrites where samples are prepared using solid-state reaction technique. The impact of V 5+ substitution on structural, magnetic, dielectric and electrical properties has been studied. XRD analysis confirms formation a single-phase cubic spinel structure. lattice constants calculated both theoretically experimentally along with other structural parameters such as bulk density, x-ray density porosity. FESEM images studied for analyzing surface morphology. FTIR measurement structure formation. saturation magnetization ( M s ), coercive field H c ) Bohr magnet ? B from obtained M-H loops. temperature-dependent permeability is to obtain Curie temperature. frequency composition dependence also analyzed. Frequency dependent behavior ac resistivity investigated. An inverse relationship observed between constant resistivity. results resistivity, magnetic suggest appropriateness in microwave device applications.
