The complex refractive index has been determined for graphene for linearly polarised light in p- and s-geometry at energies across the carbon 1s edge. The imaginary part was measured with absorption spectroscopy. The real part was derived using Krame

The mechanical setup of a novel scanning reflection X-ray microscope is presented. It is based on zone plate optics optimized for reflection mode in the EUV spectral range. The microscope can operate at synchrotron radiation beamlines as well as at l

Many physical effects are strongly depending on the composition of the interfaces between separating layers. Hence, the knowledge of the interfacial characteristics such as structure, chemical bonds, or magnetic properties of the corresponding materi

Using polarization analysis of linearly polarized synchrotron radiation we demonstrate the existence of a giant magneto-optical Faraday effect at the carbon $1s$ edge of single-layer graphene on Co, reaching Faraday rotation angles of $2.9\ifmmode\ti

The existence of ferromagnetic ordering in graphene on cobalt is demonstrated by means of resonant magnetic reflection spectroscopy exploiting the transversal magneto-optical Kerr-effect (T-MOKE). Using linearly polarized synchrotron radiation in the

The existence of natural birefringence in x-ray reflection on graphene is demonstrated at energies spanning the carbon $1s$ absorption edge. This new x-ray effect has been discovered with precision measurements of the polarization-plane rotation and

Soft X-ray magnetic reflection spectroscopy with linearly polarized light was used to investigate thin Fe films close to their 3p absorption edges. The high reflectivity in this spectral range enables one to measure magnetic signals in a wide angular

The magnetic coupling in Co/Cu multilayers with individual layer thicknesses tuned to the 2nd maximum of the giant magnetoresistance (GMR) is investigated by soft X-ray magnetic scattering. A series of half-integer order magnetic peaks appears in the
