Abstract
A Fe/Cu/Co/Cu multilayer exhibiting an hysteresis loop with two charac teristic coercive fields which can be assigned separately to the two m agnetic 3d metals has been studied. XMCD measurements are able to foll ow the field dependent element-specific magnetisation. The photon heli city was reversed using a diamond quarter-wave plate in Laue geometry. XMCD and macroscopic magnetisation measurements are in agreement and show that in this multilayer system the Co layer reverses magnetisatio n direction at a lower field than the Fe layer.
