摘要：

We have prepared the ternary nitride Gd2Fe17N(x) (with x close to 3) and have studied this compound by means of X-ray diffraction and Gd-155 Mossbauer spectroscopy. Our results show that X-ray diffraction is not always a sufficient means to test whether the charging process with N2 gas has reached completion. From the analysis of the Gd-155 Mossbauer spectrum of Gd2Fe17N(x) it is derived that the electric field gradient at the Gd nuclei is 12.6(2)x10(21) V/m2. This value is substantially larger than that found at the Gd sites in Gd2Fe14B. Its implication on the crystal field induced anisotropy in R2Fe17N(x) compounds is discussed.
