    We have synthesized a Ba[sub 6]Ge[sub 25] clathrate, substituting 3 Ge per formula unit by Fe. This chiral clathrate has Ge sites forming a framework of closed cages and helical tunnel networks. Fe atoms randomly occupy these sites, and exhibit high-spin magnetic moments. A ferromagnetic...

    In this letter, we performed first principles calculations to investigate the stability of a [100]-compatible Ge2Mn compound. Based on a thermodynamical approach, we propose and assess the C16 structure (Al2Cu prototype) to be only slightly metastable as compared to the other Ge–Mn...

    We assessed the equilibrium concentration (CVeq) and diffusivity (DV) of vacancies (V) in Ge as a function of temperature from a detailed analysis of the diffusion behavior of Co in electronic-grade Ge wafers. Diffusion experiments were performed with the radiotracer 57Co over the temperature...

    In this letter, we first show electrical spin injection in the germanium conduction band at room temperature and modulate the spin signal by applying a gate voltage to the channel. The corresponding signal modulation agrees well with the predictions of spin diffusion models. Then, by setting a...
