Epitaxial growth of Fe3O4 thin films on ZnO and MgO substrates
A. Müller, A. Ruff, M. Paul +9
Magnetite thin fims have been grown epitaxially on ZnO and MgO substrates using molecular beam epitaxy. The film quality was found to be strongly dependent on the oxygen partial pr…
Direct observation of interacting Kondo screened 4f moments in CePt5 with XMCD
C. Praetorius, A. Koehl, B. Muenzing +2
We use x-ray absorption and magnetic circular dichroism to study electronic configuration and local susceptibility of CePt5/Pt(111) surface alloys from well above to well below the…
Exploring small energy scales with x-ray absorption and dichroism
C. Praetorius, M. Zinner, P. Hansmann +2
Soft x-ray linear and circular dichroism (XLD, XMCD) experiments at the Ce M edges are being used to determine the energy scales characterizing the Ce degrees of freed…
Electronic tuneability of a structurally rigid surface intermetallic and Kondo lattice: CePt / Pt(111)
C. Praetorius, M. Zinner, A. Köhl +10
We present an extensive study of structure, composition, electronic and magnetic properties of Ce--Pt surface intermetallic phases on Pt(111) as a function of their thickness. The…
