Usually, it is grown by conventional solid state reaction of manganese with germanium using molecular beam epitaxy. Here, we report the structural and magnetic properties of Mn5Ge3 layers grown on Ge substrates using ultrafast-solid phase epitaxy (SPE) method. We investigate the influence of the substrate orientation, Mn layer thickness and annealing parameters on the crystallographic orientation and magnetization of Mn5Ge3. It is shown that after millisecond range SPE, Mn5Ge3 films always have a preferred (100) orientation whether grown on Ge (001) or (111) substrates, which determines the orientation of the magnetization easy axis lying in the film plane along c axis independent of the layer thickness. The Curie temperature of Mn5Ge3 weakly depends on fabrication parameters.}, language = {en} } @misc{WeisshauptFunkKernetal., author = {Weißhaupt, David and Funk, Hannes S. and Kern, Michal and Dettling, Marco M. and Schwarz, Daniel and Oehme, Michael and S{\"u}rgers, Christoph and Slageren, Joris van and Fischer, Inga Anita and Schulze, J{\"o}rg}, title = {Weak localization and weak antilocalization in doped Ge1-ySny layers with up to 8\% Sn}, series = {Journal of Physics: Condensed Matter}, volume = {33}, journal = {Journal of Physics: Condensed Matter}, number = {8}, issn = {1361-648X}, doi = {10.1088/1361-648X/abcb68}, pages = {8}, language = {en} } @misc{FunkKernWeisshauptetal., author = {Funk, Hannes S. and Kern, Michael and Weisshaupt, David and S{\"u}rgers, Christoph and Fischer, Inga Anita and Oehme, Michael and Slageren, Joris van and Schulze, J{\"o}rg}, title = {Magnetic Characterization of a Mn Based Ferromagnet on SixGe(1-x-y)Sny with High Sn Content}, series = {ECS Transactions}, volume = {93}, journal = {ECS Transactions}, number = {1}, issn = {1938-5862}, doi = {10.1149/09301.0101ecst}, pages = {101 -- 104}, language = {en} }
