采用水热法制备了掺杂稀土元素镨(Pr)的铁氧化钴CoPrxFe2-xO4（x=0.0、0.01、0.025、0.05、0.075、0.1）纳米颗粒．实验结果表明制备出来的样品是立方体结构的纳米颗粒,当掺杂量0<x≤0.1的时候Pr3+离子成功的能掺杂到CoFe2O4晶格内，但掺杂量x >0.1(x =0.15)时出现杂峰．随着掺杂量从0增加到0.1时，样品的平均晶格尺寸从34nm 减小到15nm，饱和磁化强度(Ms)从78emu/g 单调减小至36emu/g，矫顽力从1008Oe 降低到668Oe ．

Rare earth element praseodymium-doped CoPrxFe2-xO4 (x=0.0, 0.01, 0.025, 0.05, 0.075, 0.1)magnetic nanoparticles were successfully synthesized by the hydrothermal method. The results show that prepared samples are cubic structural nanoparticle, when the dopant amount in the range 0<x 6 0.1, we have not observed any trace of impurity peaks which confirms that, Pr3+ions have been incorporated into the cobalt ferrite lattice, but when its value over the 0.1, impurity peak occurs. With the increase in dopant amount from 0 to 0.1, the average crystallite size decreases from 34nm to 15nm, saturation magnetization (Ms) monotone reduces from 78emu/g to 36emu/g and coercivity decreases from 1008Oe to 668Oe.
