Abstract
The Sm-Fe exchange field and the two main crystalline electric field p arameters A(2)(0) and A(4)(0) in Sm2Fe17Nx (0 less than or equal to x less than or equal to 3.0) are determined by analyzing the available e xperimental data. It is deduced that the Sm-Fe exchange field decrease s and the absolute value of A(2)(0) increases linearly with increasing N concentration. The decrease in the Sm-Fe exchange field is discusse d in terms of the hybridization interactions of Sm 5d states with Fe 3 d and N 2p states.
