Study structural, surface morphological and magnetic properties of Mn(1-x) Znx Fe2O4 by solid state reaction method

Abstract

The powder of Mn-Zn ferrite having the chemical formula Mn_(1-x)Zn_xFe₂O₄ where x varies from 0, 0.1, 0.2, 0.3, 0.4, and 0.5 were synthesized by solid state Reaction method. The X-Ray Diffraction studies confirm the formation of spinel cubic structure. The particle size was calculated by X-ray broadening studies. Also the structural parameters like Lattice Constant, X-ray density, bulk density (d), Porosity (P), ionic radius (R_a , R_b) and anion parameter or the oxygen positional parameter  for all the samples. The micro structural features of the samples were obtained using a Scanning Electron Microscopy (SEM). The magnetic properties of Mn_(1-x)Zn_xFe₂O₄ ferrites were strongly affected by the Zn content. The saturation magnetization increased. It may be due to relatively high orbital contribution of Mn²⁺ ions to magnetic moment, which gives large induced anisotropy.
