Electronic Structure and Interplay of Atomic and Magnetic Orders of Alloys with Narrow $d$-Bands

In the review, results of investigation of interplay of atomic and magnetic orders in alloys with narrow d-bands are presented. The basic theoretical approaches to a description of the disordered alloys with strong electron correlations are considered, and validity ranges of these approaches are outlined. The interplay between the changes of atomic and magnetic orders in such alloys and the realignment of their electron energy spectrum is analysed.
