  • 摘要

    本文在1.5—300K温度范围内测量了R2Fe14B(R=Ce,Pr,Gd)各向异性常数K1,K2和各向异性场HA随温度的变化。同时用单离子模型计算了Pr3+离子对Pr2Fe14B磁晶各向异性的贡献,得到与实验值半定量符合的结果。

     

    Abstract

    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.
