Short description of the research topics:

The correlation of the experimental data obtained from static magnetic measurements (magnetization and magnetic susceptibility as a function of temperature and magnetic field) and X-ray photoelectron spectroscopy (XPS- spectra) contributes to a better understanding of the magnetic phenomena and to a correct interpretation of the magnetic properties of the intermetallic compounds based on transition elements.
