MethodsNEXAFS, XMCD, Photoelectron EM, X-ray Microscopy
This microscope is equipped with a new state-of-the-art aberration corrector minimizing electron-optical imperfections, allowing for higher instrument transmission and simultaneously better spatial resolution. In LEEM-Mode, 2 nm have been demonstrated recently. In combination with soft x-rays (XPEEM), spatially-resolved spectroscopic investigations can be carried out (NEXAFS, XPS) as well as magnetic spectroscopies (XMCD,XMLD). A recently installed extension allows to perform stroboscopic XPEEM experiments for magnetization dynamics.
