Interface-driven phase separation in multifunctional materials: the case of GeMn ferromagnetic semiconductor
Emmanuel Arras, Frédéric Lançon, Ivetta Slipukhina +11
We use extensive first principle simulations to show the major role played by interfaces in the mechanism of phase separation observed in semiconductor multifunctional materials. W…

Exchange bias in GeMn nanocolumns: the role of surface oxidation
S. Tardif, S. Cherifi, M. Jamet +9
We report on the exchange biasing of self-assembled ferromagnetic GeMn nanocolumns by GeMn-oxide caps. The x-ray absorption spectroscopy analysis of this surface oxide shows a mult…

Strain and correlation of self-organized Ge_(1-x)Mn_x nanocolumns embedded in Ge (001)
S. Tardif, V. Favre-Nicolin, F. Lançon +8
We report on the structural properties of Ge_(1-x)Mn_x layers grown by molecular beam epitaxy. In these layers, nanocolumns with a high Mn content are embedded in an almost-pure Ge…
