摘要：

The compound Er2Fe17C2.5 formed by melt spinning has the rhombohedral Th2Zn17-type structure. The spin reorientation transition occurs at about 136 K. The Fe-57 Mossbauer effect was measured in the temperature range 12-300 K. From the acceptable fit we find that the effective hyperfine fields of various sites decrease in the order 6c > 18f > 18h > 9d. The anisotropy of the effective hyper-fine field is observed to be different for different sites. The temperature dependence of the quadrupole splitting shows a large increase at around T(sr) with increasing temperature.
