Abstract

A longstanding theoretical prediction is the orientation of spins by an electrical current flowing through low-dimensional carrier systems of suffciently 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 temperature. (PDF)
