Abstract

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 ¹⁵⁵Gd Mössbauer 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 ¹⁵⁵Gd Mössbauer spectrum of Gd₂Fe₁₇N_x it is derived that the electric field gradient at the Gd nuclei is 12.6(2)×10²¹ 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.
