| Abstract: | Crystal structures and magnetic properties of R13Fe74Si13 (R = Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Y) alloys are investigated in this paper. The results show that R13Fe74Si13 alloys have pseudobinary intermetallic compound R2(Fe0.85Si0.15)17 as the main phase instead of forming a ternary compound of the type R2Fe14B. The Si atoms probably substitute for Fe atoms in R2Fe17 (9d site in Th2Zn17 or 6g site in Th2Ni17). Curie temperatures of R13Fe74Si13 alloys are comparably higher than that of R2Fe17. Saturation magnetization and magnetic anisotropy at room temperature were measured. Based on the results of extracting sample measurement at low temperatures the variation of the magnetization of R13Fe74 Si13 with temperature was discussed. |
