Studies on composition dependent structural and magnetic characterization of nano-crystalline cadmium doped nickel ferrite

Abstract

Using self-ignited auto-combustion method, Cd doped Ni-Zn Ferrite nano-structures were prepared. Samples were characterized to determine their composition dependent structural and magnetic properties. XRD patterns of as-prepared specimens’ revealed cubic spinel structure (single phase). Raman spectra disclosed five active modes consistent to the spinel phase. Magnetic properties of these ferrites were determined in terms of saturation magnetization, magnetic moment. Mossbauer spectra recorded at 300 K temperature Variations of isomer shift, hyperfine field, quadrupole splitting and line width are analyzed with the amount of doped Cadmium.Using self-ignited auto-combustion method, Cd doped Ni-Zn Ferrite nano-structures were prepared.
