摘要
实验表明ＧｄＣｏ５与ＹＣｏ５的磁晶各向异性能存在一定差距．本文采用点电荷模型，考虑过渡族离子和稀土离子对晶场势的贡献，以自旋轨道耦合与晶场势为微扰哈密顿量，计算了ＧｄＣｏ５中Ｇｄ３＋的基态分裂和磁晶各向异性常数。
The magnetocrystalline anisotropy of GdCo 5was observed experimentally, which significantly differes from that of YCo 5. In this paper,by using the point charge model and considering the contribution of both the transiton and rare earth ions to the crystal field, the ground state splitting and the magnetocrytalline anisotropy of Gd 3+ is studied. The present results qualitatily explain the existence of the magnetocrystalline anisotropy of the GdCo 5.
