  Abstract


  We have studied the structural and magnetic properties of MBE-prepared epitaxial Fe/Cr (001) oriented superlattices. The samples consist of 20 periods with 2.5 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, magneto-optical 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 field 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.

  of the magnetization.
