Abstract

Magnetic properties of Ge1-xMnx epitaxial layers with a Mn content of a few percents are substantially influenced by inhomogeneities in the distribution of Mn atoms in the Ge lattice. Depending on the substrate temperature during molecular-beam epitaxial fabrication, apparently cubic, coherent Mn-rich clusters or incoherent precipitates consisting of the hexagonal, intermetallic Mn5Ge3 phase can ...
