摘要：

This study successfully synthesized Mg 0.5 Ni 0.5 Fe 2- x Nd x O 4 ( x =0, 0.01, 0.03, 0.05) spinel ferrites using the sol-gel method. X-ray diffraction analysis revealed that doping with Nd 3+ enhanced lattice distortion, and a secondary NdFeO 3 phase emerged at higher concentrations. Mössbauer spectroscopy analysis revealed that Nd 3+ doping modified the distribution of metal cations within the samples and yielded theoretical values for the samples’ magnetic moments. Magnetic analysis indicated that magnetic parameters, including saturation...
