Edge spin accumulation in semiconductor two-dimensional hole gases
K. Nomura, J. Wunderlich, Jairo Sinova +3
The controlled generation of localized spin densities is a key enabler of semiconductor spintronics In this work, we study spin Hall effect induced edge spin accumulation in a two-…
Low-temperature magnetization of (Ga,Mn)As semiconductors
T. Jungwirth, J. Masek, K. Y. Wang +12
We report on a comprehensive study of the ferromagnetic moment per Mn atom in (Ga,Mn)As ferromagnetic semiconductors. Theoretical discussion is based on microscopic calculations an…
Co-planar spin-polarized light emitting diode
B. Kaestner, J. Wunderlich, Jairo Sinova +1
Studies of spin manipulation in semiconductors has benefited from the possibility to grow these materials in high quality on top of optically active III-V systems. The induced elec…
Charge Hall effect driven by spin-dependent chemical potential gradients and Onsager relations in mesoscopic systems
E. M. Hankiewicz, Jian Li, Tomas Jungwirth +3
We study theoretically the spin-Hall effect as well as its reciprocal phenomenon (a transverse charge current driven by a spin-dependent chemical potential gradient) in electron an…
Prospects of high temperature ferromagnetism in (Ga,Mn)As semiconductors
T. Jungwirth, K. Y. Wang, J. Masek +11
We report on a comprehensive combined experimental and theoretical study of Curie temperature trends in (Ga,Mn)As ferromagnetic semiconductors. Broad agreement between theoretical…
