Abstract
The interfacial coupling between Gd(0001) and Fe(110) in an epitaxial Gd/Fe bilayer has been studied by means of magnetometry and polarized neutron reflectivity with spin analysis. The results are interpreted i n terms of a Gd twisted spin state in low applied fields. This origina l magnetic configuration was examined by theoretical calculations and found to be due to competing Gd-Gd and Gd-Fe exchange interactions wit h the Gd-Fe exchange interactions being long ranged and oscillatory.
