摘要：

We have investigated proximity effects of Fe layers on the spin density waves (SDW) in thin epitaxial Cr[001] films with neutron scattering. Unlike in bulk Cr we observe a strong anisotropic occupation of the three possible SDWs. In pure Cr[001] films the SDWs exhibit an almost complete out-of-plane propagation with spins parallel to Q. With only 20 A Fe on top of these Cr films, the SDW becomes completely re-oriented with Q now propagating in the plane but the Cr-spins still point out of the plane. This implies that the Fe and Cr moments are oriented perpendicular to each other.
