Abstract: The Ni0.3Cu0.2Zn0.5YxFe2-xO4 (where x= 0, 0.025, 0.05, 0.075, 0.1) ferrite with Y3+ substituted partial Fe3+ was synthesized by sol-gel method at 950 ℃. The structure and magnetic properties of the sample were studied. It was found that a small amount of Y3+ doping does not destroy the crystal structure of Ni-Cu-Zn ferrite, but when the doping amount is more than 0.025, a small amount of YFeO3 foreign phase is formed. As the doping amount increases, the lattice constant first decreases and then increases, and the grain size and saturation magnetization increase first and then decrease. Compared with pure Ni0.3Cu0.2Zn0.5Fe2O4 ferrite, the coercivity, remanence, squareness ratio and Curie temperature of the doped samples increased, but all samples showed a paramagnetism. When the doping amount is 0.025, the saturation magnetization reaches 68.98 emu/g, and the Curie temperature increased to 215 ℃.
