Abstract

X-ray absorption spectroscopy of epitaxial GeMn thin films reveals an experimentally indistinguishable electronic configuration of Mn atoms incorporated in Ge(1-x)Mn(x) nanoclusters and in precipitates of the intermetallic compound Mn(5)Ge(3), respectively. However, the average magnetic response of thin films containing Ge(1-x)Mn(x) nanoclusters is lower than the response of films containing ...
