| Abstract: | 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. |
