TEMPERATURE DEPENDENCE OF THE ANISOTROPY CONSTANTS K1 AND K2 OF R2Fe14B(R=Ce, Pr, Gd)
R2Fe14B(R=Ce,Pr,Gd)磁晶各向异性常数K1,K2随温度的变化

The temperature dependence of the anisotropy constants K1, K2 and the anisotropy field HA. of R2Fe14B (R = Ce, Pr, Gd) have been measured in temperature range of 1.5 K to 300 K. And the contribution of Pr3+ ions to the magnetocrystalline anisotropy of Pr2Fe14B compound was calculated by the single ion theory. The result is semiquantitatively consistent with the experiment.
