dc.description.abstractMany technological aspects of everyday life are based on practical applications of the magnetic properties of the materials. Miniaturization is a key technological aspect; electronic circuits and storage devices are nowadays steadily decreasing in size and will eventually reach molecular dimensions. The understanding and predictions of the properties of matter at atomic levels represents one of the great achievements of the last years in science. In the present thesis, the aim is to present a complete study of the electronic structure of selected materials, by means of experimental and theoretical methods. The class of materials which are presented in this thesis, are belonging to the magnetic molecules and intermetallic compounds. The electronic structure of the single molecule system named ferric star molecule has been studied. From the resonant X-ray emission study the trend observed for the FeFe3 star gives a signature for the high-spin structure, or more precisely of strong magnetic systems like FeO or Heusler alloys. For the case of intermetallic alloys and compounds, the Mn 2p core-level presents a visible split structure, which is arising from the exchange interactions between the core-hole and the unpaired 3d electrons. The interpretation of this splitting can be regarded as an evidence of local magnetic moments belonging to the Mn site.eng
