摘要：

This paper presents the results of calculations of the magnetic moment distribution in the framework of the tight-binding Hubbard model and the Anderson periodic model for spatially nonhomogeneous systems (stepped surfaces of Fe and Cr, monolayer coverings on such surfaces). These data are used for a description of recent experiments with low-dimensional FeCr magnetic systems.
