Abstract
Over the last 25 years, x-ray absorption near edge structure (XANES) and x-ray magnetic circular dichroism (XMCD) have proven to be particularly suitable for the study of the electronic and magnetic properties of uranium compounds. The use of magneto-optical sum rules can provide the possibility of disentangling the spin and orbital contribution to the total magnetic moment carried by the absorbing atom, and to determine both their magnitudes and their signs. XMCD also offers the possibility of element selective magnetization. In this review, the strengths of XANES/XMCD are illustrated by selected examples of uranium compounds, such as molecular magnets, strongly correlated electron systems (paramagnet, ferromagnetic superconductor, metamagnet and antiferromagnet) and uranium-based multilayers investigated at the ESRF beamline ID12. Some perspectives, initiated by recent experimental developments, are also given.
