Structural and magnetic characterizations have been combined to investigate the growth kinetics of Ge1−x Mnx diluted magnetic semiconductors (DMSs) on Ge(001) substrates by means of molecular beam epitaxy (MBE). We have identified the growth process window allowing stabilization of a high Curie temperature (TC) nanocolumn phase and provide evidence that the growth of semiconducting Ge1−x Mnx nanocolumns and metallic Mn5Ge3 clusters is a competing process. Due to a continuous increase of the Mn… CONTINUE READING
