摘要	The crystal structure and magnetic properties of Nd1-xRxCo3 (R = Gd, Th) have been investigated by means of X-ray powder diffraction and magnetic measurements. Spin reorientation and magnetization compensation are observed in both systems. The saturation magnetization M-s of Nd1-xTbxCo3 exhibits an anomaly at a critical concentration x(c) approximate to 0.55, whereas no such an anomaly is observed for Nd1-xGdxCo3. These observations could be understood by considering the difference of the anisotropy between Tb3+ and Gd 31 ions. The type of magnetocrystalline anisotropy of the compounds is derived based on X-ray diffraction patterns of the field-aligned samples. For Nd1-xTbxCo3 the anisotropy near x(c) is weak with an undefined easy magnetization direction. On the Nd-rich side, the anisotropy exhibits a strong temperature dependence.
