Structural and optical properties of self-catalytic GaAs:Mn nanowires grown by molecular beam epitaxy on silicon substrates
Katarzyna Gas, Janusz Sadowski, Takeshi Kasama +7
Mn-doped GaAs nanowires were grown in the self-catalytic growth mode on oxidized Si(100) surface by molecular beam epitaxy and characterized by scanning and transmission electron m…
Depth dependent magnetization profiles of hybrid exchange springs
T. N. Anh Nguyen, R. Knut, V. Fallahi +8
We report on the magnetization depth profile of a hybrid exchange spring system in which a Co/Pd multilayer with perpendicular anisotropy is coupled to a CoFeB thin film with in-pl…
Water Adsorption at the Tetrahedral Titania Surface Layer of SrTiO(110)-(41)
Zhiming Wang, Xianfeng Hao, Stefan Gerhold +6
The interaction of water with oxide surfaces is of great interest for both fundamental science and applications. We present a combined theoretical [density functional theory (DFT)]…
Large lattice distortions associated with the magnetic transition in La0.7Sr0.3MnO3
F. Weber, D. Argyriou, O. Prokhnenko +1
Colossal magnetoresistance (CMR) is associated with the phase transition from a metallic ferromagnetic to insulating paramagnetic phase, which can be controlled by an applied magne…
Effect of low-temperature annealing on the electronic- and band-structure of (Ga,Mn)As epitaxial layers
O. Yastrubchak, T. Andrearczyk, J. Z. Domagala +4
The effect of outdiffusion of Mn interstitials from (Ga,Mn)As epitaxial layers, caused by post-growth low-temperature annealing, on their electronic- and band-structure properties…
Electronic- and band-structure evolution in low-doped (Ga,Mn)As
O. Yastrubchak, J. Sadowski, H. Krzyzanowska +5
Modulation photoreflectance spectroscopy and Raman spectroscopy have been applied to study the electronic- and band-structure evolution in (Ga,Mn)As epitaxial layers with increasin…
