【 摘 要 】

First experiments along with the general capabilities of the TTXMCD endstation at P04, PETRA III, DESY are presented. The TTXMCD endstation allows measuring the magnetic properties of solids, thin films, molecules or atomic adsorbates at ultra-cold temperatures in an element specific way. At such temperatures, electron-electron interaction phenomena are studied, such as the Kondo effect for Co on Cu(100).
