Abstract
Magnetic ordering is studied in Cr/X (1 ML) layer structures with monatomic layers (ML) of nonmagnetic metals (X = Sn, V, Ag, Au) incorporated into a chromium matrix. The mechanism associated with a redistribution of the charge and spin densities near the Cr/X interface and through which a spin-density wave (SDW) is induced and modified in these systems is analyzed. A semiphenomenological model is considered in detail in terms of which SDW structure near a single planar nonmagnetic defect can be described qualitatively using the Ginzburg-Landau functional. The spatial SDW configuration in a [Cr(t/X(1 ML)] superlattice is calculated, and the dependences of the SDW parameters on the temperature T, type of metal X, and superlattice period t are established. Based on the results of the study, experimental Mössbauer spectroscopy data are interpreted.
