Structural, electrical and magnetic studies of neodymium substituted nickel ferrite nanoparticles

Nanoparticles NiFe2-xNdxO4 (x=0.0, 0.05, 0.1, 0.15) ferrite was prepared by solgel combution method. The samples were characterized with X-ray diffraction and SEM measurements. The effect of Nd3+ cations substitution on structure of prepared nano particles was investigated. From the analysis, the system was found to be inverse spinal cubic structure. The lattice parameter (a) increases with Nd doping content. Room temperature DC electrical resistivity decreases. Magnetic studies by Vibrating Sample Magnetometer (VSM) shows that magnetization (Ms) decreases with increase in Nd3+ concentration. Coercivity (Hc) first decreases for x=0.05, after which it increases up to x=0.15.
