Chiral Magnetic Domain Structures in Ultrathin FePd Films

Abstract

The magnetization profile of magnetically ordered patterns in ultrathin films was determined by circular dichroism in x-ray resonant magnetic scattering (CDXRMS). When this technique was applied to single crystalline iron palladium alloy layers, magnetic flux closure domains were found whose thickness can constitute a large fraction ( approximately 25 percent) of the total film.
