摘要：

In this paper we present Fe-57 Mossbauer spectra of a new ternary intermetallic phase Nd2(Fe, Ti)19 and its nitride. Our previous work suggests that the 2-19 phase is related to the hexagonal TbCu7 structure. The average Fe-57 magnetic hyperfine field of Nd2(Fe, Ti)19 at 295 K is 20.8 T which corresponds to an average Fe atomic magnetic moment of 1.33 mu(B). After nitrogenation, the average Fe-57 hyperfine field at 295 K is 29.6 T, which corresponds to an average Fe atomic magnetic moment of 1.90 mu(B). This enhancement in the Fe atomic magnetic moment (at 295 K) is attributed mainly to the N-induced increase in Curie temperature of about 200 K.
