First-principles study of spin-density waves in Fe/Cr and V/Cr multilayers

A first-principles electronic structure calculation for Fe/Cr and V/Cr multilayers is performed, and spin-density wave order in the Cr layer is investigated. It is found that for a sufficiently large spacer thickness of the Cr layer the spin-density wave order grows spontaneously and becomes similar to that in bulk Cr in the vicinity of the middle of the Cr layer.
