Strain controllable magnetocrystalline anisotropy in FeRh/MgO bilayers
Henry Hoffmann, Eun Sung Jekal
Ultra-thin film of FeRh on insulator MgO substrate has been investigated usingab-initio electronic structure calculations. From this calculation, we have found the interesting effe…
Non-thermal photocoercivity effect in a ferromagnetic semiconductor
G. V. Astakhov, H. Hoffmann, V. L. Korenev +7
We report a photoinduced change of the coercive field, i.e., a photocoercivity effect (PCE), under very low intensity illumination of a low-doped (Ga,Mn)As ferromagnetic semiconduc…
Mott-Hubbard gap closure and structural phase transition in the oxyhalides TiOBr and TiOCl under pressure
C. A. Kuntscher, A. Pashkin, H. Hoffmann +9
Pressure-dependent transmittance and reflectance spectra of TiOBr and TiOCl single crystals at room temperature suggest the closure of the Mott-Hubbard gap, i.e., the gap is filled…
Pressure-induced metallization and structural phase transition of the Mott-Hubbard insulator TiOBr
C. A. Kuntscher, S. Frank, A. Pashkin +9
We investigated the pressure-dependent optical response of the low-dimensional Mott-Hubbard insulator TiOBr by transmittance and reflectance measurements in the infrared and visibl…
Optical spin pumping of modulation doped electrons probed by a two-color Kerr rotation technique
H. Hoffmann, G. V. Astakhov, T. Kiessling +5
We report on optical spin pumping of modulation electrons in CdTe-based quantum wells with low intrinsic electron density (by 10^10 cm^{-2}). Under continuous wave excitation, we r…
