摘要：

Rare earth（RE） low doping has a significant influence on the structural,morphological,and magnetic properties of spinel ferrite nanoparticles.Therefore,rare earth neodymium（Nd） oxide was fully doped into spinel ferrite with a composition of Co0.80Ni0.20NdxFe2-xO4（x=0.0,0.05,0.10,and 0.15） using the sol-gel auto combustion method.Structural analysis of the synthesized samples with low doping of Nd using X-ray diffraction（XRD） and Rietveld refinements reveals a pure single-phase cubic structure,while the second phase appears with increasing content of Nd3+ at x=0.10 and 0.15.Scanning electron microscopy（SEM） and high-resolution transmission electron microscopy（HR-TEM） show well-shaped spherical grains within the nanometer range of the pure Co0.80Ni0.20Fe2O4 sample,while larger grains with the presence of agglomeration are observed with doping of Nd3+into the spinel ferrite nanoparticles.The magnetic parameters,i.e.,saturation magnetization Ms,remanence and magnetic moments exhibit decreasing trend with Nd3+doping and Ms values are in 65.69 to 53.34 emu/g range.The coercivity of the Nd-doped Co-Ni spinel ferrite sample was calculated to be 1037.76 to ～827.24 Oe.This work demonstrates remarkable improvements in the structural and magnetic characteristics of Nddoped Co-Ni spinel ferrite nanoparticles for multiple versatile applications.
