Design of a X-ray zone plate microscope for magnetic domain imaging in the EUV range — •Andreas Schümmer1, Markus Gilbert1, Christine Jansing1, Hans-Christoph Mertins1, Roman Adam2, Claus Schneider2, Larissa Juschkin3, and Ulf Berges41University of Applied Sciences,FH Münster, 48565 Steinfurt, Germany, — 2Forschungszentrum Jülich, Peter Grünberg Institut (PGI-6), 52428 Jülich, Germany — 3Rheinisch-Westfälische Technische Hochschule Aachen, 52062 Aachen, Germany — 4TU Dortmund, Zentrum für Synchrotronstrahlung, 44227 Dortmund, Germany

We present a new design of a Scanning Reflection X-ray Microscope (SRXM) based on zone plate imaging in the extreme ultraviolet (EUV) spectral range at the DELTA beamline 12 optimized for the 3p absorption edges of 3d transition metals. The operation in reflection mode will allow magnetic domain imaging in buried layers exploiting magneto-optical reflection spectroscopy employing T-MOKE, L-MOKE, XMLD and XMCD [1] as magnetic contrast mechanisms. In contrast to transmission, the STXM geometry will allow the study of buried layers, layer systems and interfaces on surfaces even of thick samples. The advantage of the EUV spectral range over the soft X-ray range is the increased reflectance which is about two orders of magnitude larger than at the 2p edges. [1] M. Tesch, M. Gilbert, H - Ch.
