Applications of circularly polarized x-rays are becoming increasingly important. A major use is in x-ray magnetic circular dichroism (XMCD). With this technique, the magnetic, chemical and physical properties of systems which contain magnetic or paramagnetic atoms can be studied. The Advanced Light Source (ALS), a 3rd generation synchrotron light source, has several beamlines which are operating or are under construction which employ XMCD. This paper highlights some of these applications, including studies of magnetic materials, where XMCD can determine the element specific magnetic moments in systems having giant moments or colossal magnetoresistance. Investigations of biomolecules have also been performed, studying the structure and spin state of transition metal centers in metalloproteins. New beamlines and other applications such as magnetic microscopy are also discussed.
