摘要：
The ternary Pr2Er(Fe,Ti)(29) and SmNd2(Fe,Ti)(2), intermetallic compounds were successfully synthesised and crystallographically and magnetically characterised. The anisotropy constants, the anisotropy field and the easy magnetization directions were determined at 5 and 300 K. The results support the idea of preferential substitution of Pr and Nd at the 4i-sites in Pr2Er(Fe,Ti)(29) and SmNd2(Fe,Ti)(29) respectively, and thus the observed changes in anisotropy arise due to the difference in the Stevens factors between the substituting and substituted ions.
