Abstract

Zn 0.8Co0.2O epitaxial films have been grown by reactive magnetron sputtering and investigated with regard to the local structural properties, valence, and magnetism using x-ray absorption spectroscopy and both linear as well as magnetic circular dichroism. Samples were found to be phase pure and paramagnetic even at the coalescence of the Co doping and a small magnetic polarization of the Zn can be inferred. The changes of structure, valence, and magnetism upon increasing the oxygen content in the sputter gas are researched as well.
