In this paper, we report investigations concerning the fabrication of a diluted Ge(Mn) solution using solid state Mn diffusion, and Mn/Ge reactive diffusion for spintronic applications. The study of Mn diffusion shows that the quasi-totality of the incorporated Mn atoms occupies Ge substitutional sites and probably exhibits two negative elementary charges.(More)
The diffusion of a half monolayer of Mn deposited by molecular beam epitaxy on a Ge(0 0 1) substrate was studied via secondary ion mass spectrometry. Mn diffused in Ge under extrinsic conditions, exhibiting a solubility of 0.7–0.9%. All the Mn atoms were activated, occupying Ge substitutional sites and exhibiting a negative charge, in agreement with(More)
