X-PEEM


Magnetic nanostructures are at the heart of modern data storage technology. Typical dimensions of magnetic bits are in the sub-100nm region. In addition novel magnetoelectronics devices such as magnetic random access memory junctions are operated on the sub-100nm m scale. An understanding magnetic properties of such low-dimensional structures is only accessible to spectro-microscopy tools capable of appropriate lateral resolution. This goal is achieved by combining a novel spin-resolved photoemission microscope (SPEEM) with a dedicated microfocus PGM beamline with full x-ray polarization control (UE49-PGM).

The synergy between the microscopy capabilities of the PEEM and the polarization control of synchrotron radiation makes of X-PEEM the ideal tool for space resolved and element selective investigation of nanostructures by means of chemical maps (XAS) and  magnetic imaging (XMCD and XLD).
