“…2 However, during the last decade, the development of techniques with element specificity and monolayer sensitivity, such as x-ray magnetic circular dichroism ͑XMCD͒, 3 permits a more systematic study of induced ferromagnetism in thin multilayer structures. To date, most efforts have been focused on the induced magnetic moments of the 3d, 4d, and 5d transition-metal series, 4 whereas the induced magnetism of 5f elements in magnetic multilayers is still largely unexplored. Indeed, the combination of a soft magnetic element like iron and an element that possesses a large spin-orbit coupling, such as uranium, may give rise to interesting and unusual magnetic properties.…”
