Spin-density-wave ordering in chromium-based layered structures with the insertion of nonmagnetic monatomic layers

Abstract

The magnetic structure of $\mathrm{Cr}∕X$ layered systems with inserted nonmagnetic monolayer $X$ is studied within the Ginzburg-Landau functional approach. The mechanism of the spin-density-wave (SDW) ordering, induced by the plane defect, is proposed. The spatial distribution of the SDW order parameter is described for various temperature regions, different kinds of inserted monolayers $X$ and thickness of Cr layer. The obtained results are compared with recently reported data on the M\"ossbauer spectroscopy measurements in epitaxial $X∕\mathrm{Cr}∕\mathrm{Sn}∕\mathrm{Cr}$ multilayers ($X=\mathrm{V}$, Ag, or Fe).
