We investigated the magnetic properties of a (110)-oriented multilayer of the form Å Å Å Å consisting of 260 Å thick layers and 12 Å thick layers which were grown epitaxially on a single crystal. The easy axis of magnetization is the  direction as determined by polarized neutron reflectometry. Neutron diffraction data reveal that the commensurate spin density wave is the stable phase at and the magnetic moments are aligned perpendicular to . When rotating the magnetization from the easy axis into the in-plane hard-axis direction by applying a magnetic field of the intensity of the commensurate peak decreases by a factor of 2. This can be interpreted as a simultaneous rotation of the and moments pinned together in its initial perpendicular orientation.
