Abstract
Spin-polarized low-energy electron diffraction is applied for the first time to study the coupling between ferromagnetic and antiferromagnetic ultrathin films. The remanent magnetization for the epitaxial double-layer structure /Cr//Cr(100) has been monitored in situ during growth. The two Fe slabs (, ) separated by a thin Cr layer show in-plane antiparallel magnetic coupling along the external magnetic field direction when the two Fe-layer thicknesses differ. The measurements suggest a 90° rotation of the antiparallel magnetization for equal Fe-layer thicknesses.
