摘要：

We have studied the structural and magnetic properties of MBE-prepared epitaxial Fe/Cr(001) oriented superlattices. The samples consist of 20 periods with 25 nm Fe and 1.3 nm Cr individual layer thicknesses. The samples were characterized by X-ray diffraction, while: the magnetic properties were determined by magnetoresistivity, magnetooptical Kerr effect, and polarized neutron reflectivity measurements. The transition from antiparallel to parallel alignment of the magnetizations in adjacent Fe layers was investigated using polarized neutron reflectivity measurements while applying a held parallel to the layers. A spin-flop transition due to the fourfold anisotropy in the Fe layers was observed at a field of 200 Oe. (C) 2000 Elsevier Science B.V. All rights reserved.
