SPEEM
Spin resolved Photoemission Microscope
SPEEM is designed for studying sub-100nm scale magnetoelectronic devices by combining a spin-resolved photoemission microscope with a dedicated microfocus beamline offering full x-ray polarization control. The synergy between the microscopy capabilities of the PEEM and the polarization control of synchrotron radiation makes X-PEEM the ideal tool for spatially resolved and element selective investigation of nanostructures by means of chemical maps (XAS) and magnetic imaging (XMCD and XLD).

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-PGMa).
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).
