A. Schreyer et al., DIRECT OBSERVATION OF A NONCOLLINEAR 50-DEGREES-COUPLED MAGNETIZATIONPROFILE IN A FE CR(001) SUPERLATTICE/, Journal of magnetism and magnetic materials, 148(1-2), 1995, pp. 189-190
Using spin polarized neutron reflectometry on molecular beam epitaxy-g
rown Fe/Cr(001) superlattices we have studied the noncollinear exchang
e coupling of the Fe layers over the Cr spacers. A surprisingly strong
exchange coupling and a non-collinear coupling angle of 50 degrees we
re discovered.
