We investigated the angular dependence of magnetization reversal in epitaxial MnPd/Fe bilayers grown on MgO 001 using combined longitudinal and transverse magneto-optical Kerr effect. Square loops, asymmetrically shaped loops, and double-shifted loops were observed as the field orientation was varied from parallel to perpendicular to the bias direction. Additionally, including the effect of an ...

The magnetic phase of thin Fe overlayers on top of a Rh~001! surface has been probed using the surface magneto-optical Kerr effect. Quite surprisingly, we have found a suppression of ferromagnetic order up to six atomic layers of Fe. Not until Fe coverage reaches above seven layers does a ferromagnetic order start to develop. The suppression of ferromagnetic order is attributed to the tetragona...
