摘要
The influence of neighboring N atoms on electronic structure and magnetic properties of Fe atoms in Fe4N with Ni4N-I and Ni4N-II structures is investigated by first-principle LMTO method. The magnetic moment (2.50 mu(B)) of Fe neighbored by one N is reduced prominently when compared to that (2.99 mu(B)) of the Fe having no N nearest neighbor and a much rapid reduction against the decrease of cell volume is indicated. Strengthened Fe-N interaction in Fe4N with Ni4N-II structure makes the Curie temperature smaller. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
