Structural and magnetic properties of erbium thin films and erbium/yttrium superlattices

The magnetic and structural properties of crystalline erbium thin films and Er/Y superlattices, grown by Molecular Beam Epitaxy, have been analyzed by x-ray scattering, bulk magnetization measurements and neutron diffraction. By comparing the data for the two systems, the effects of the interfacial strain and the artificial modulation on the magnetic behavior of the Er have been determined. Specifically, the imposed secondary periodicity in the superlattices does not cause an interruption of the modulated Er spin order at the Er/Y interfaces. The CAM and basal plane spiral in these systems are coherent through the nonmagnetic yttrium interlayers.
