Abstract

We have studied the structural properties and the magnetization density profiles in multilayers of the Heusler phase CoMnGe with three different spacer layers: V, Au, and AlO, using hard X-ray scattering, soft X-ray resonant magnetic scattering, and polarized neutron reflectivity. We have found that the spacer layer has a significant effect on the magnetization profile of the CoMnGe layer. In all cases the interlayers at the top and the bottom of the Heusler layer exhibit a reduced magnetic moment, the thickness of which depends on the spacer layer and increases from 0.5 nm for V, to 0.6 nm for Au and 1 nm for AlO.

Keywords: Heusler alloys; Defects; Site disorder; X-ray resonant magnetic scattering; Polarized neutron reflection
