摘要：

The Mossbauer spectra of Nd2Fe17 and Nd2Fe17N2.6 have been measured as a function of temperature between 85 and 295 K. The spectral fits and hyperfine parameters for Nd2Fe17 are consistent with a Wigner-Seitz analysis of the iron near-neighbor environment. The presence of nitrogen has a major effect on the hyperfine parameters of the iron on the 18f and 18h sites, the only iron sites which have nitrogen near neighbors in Nd2Fe17N2.6.
