摘要
The study of the electronic structure and magnetic properties of the Fe3-xCrxSi compound is motivated by the Mossbauer and neutron spectroscopy measurements showing unusual behaviour of Cr in such alloys. The site preferences of Cr in Fe3Si and the effect of local environment on formation of local magnetic moments are examined using self-consistent spin-polarised TB-LMTO method. The results of calculations essentially confirm the values and orientations of magnetic moments of iron and chromium atoms. However, they do not explain an experimental observation of almost equal occupation of A, B and C sites by chromium. (C) 2002 Elsevier Science B.V. All rights reserved.
