Electric current-induced spin orientation in quantum well structures.
Journal of Magnetism and Magnetic Materials 300 (1), pp. 127-131.
A longstanding theoretical prediction is the orientation of spins by an electrical current flowing through low-dimensional carrier systems of sufficiently low crystallographic symmetry. Here we show by means of terahertz transmission experiments through two-dimensional hole systems a growing spin orientation with an increasing current at room and liquid nitrogen temperatures.
