Abstract
A new method based on the periodic Anderson model is developed for a vector description of the magnetic moments near a stepped Fe/Cr interface. The me thod allows one to perform self-consistent calculations of local magnetic m oment and d-electron numbers on a given atomic site for different orientati ons of the moment relative to the quantization axis. The self-consistent so lution with minimal energy on a site under consideration is used to perform the calculation for the next step. In this approach the noncollinear magne tic structure for stepped Fe/Cr superlattices is obtained. The ground state is always noncollinear and the angle between magnetic moments of Fe layers depends on the thickness of the Cr and Fe layers. (C) 1999 Elsevier Scienc e B.V. All rights reserved.
