Structural, infrared and magnetic properties of Ni0.7Zn0.3Fe2O4+0.4wt%V2O5 synthesized using ceramic method

Abstract

In this investigation, we aimed to synthesize Ni0.7Zn0.3Fe2O4 added with 0.4wt%V2O5 by ceramic technique and the structural magnetic and dielectric properties are determined by various characterization techniques. The phase impurity over the addition of V2O5 was identified by X-ray diffraction technique. The functional group analysis by locating the absorption bands and confirmation of formation of phase was examined by infrared spectroscopy. XRD pattern reveals that all the samples have single-phase cubic spinel structure. The lattice constant (a) and x-ray density (dx) were calculated from the XRD data. Magnetic properties of Ni0.7Zn0.3Fe2O4+0.4wt%V2O5 were carried out by pulse field hysteresis loop measurement technique. We report an increase in the Saturation magnetization (Ms), Remanence magnetization (Mr) and magneton number (nB) of Ni0.7Zn0.3Fe2O4+0.4wt%V2O5 as a cause of V2O5 addition. Whereas, the value of coercivity (Hc) was drastically decreased suggesting the changed magnetic parameters. This investigation focused on the characteristic effect of additive 0.4wt%V2O5 on physical properties of Ni0.7Zn0.3Fe2O4 ferrite.
