In the end of 2017, a photoemission electron microscope was successfully installed at the SOLARIS' PEEM/XAS beamline. For the first time in Poland, synchrotron radiation was used to image the sample surface with chemical and magnetic resolution.

Several samples were under investigation during extensive XAS measurements. The most spectacular one was the permaloy sample on silicon substrate with Co spacer and Al capping aluminium layer (1nm Al / 2nm NiFe / 20nm Co / Si). On the lithographically modified sample surface, one could observe nano- and micro- structures with different magnetic domains.
