Abstract :
A new type of infrared induced photocurrents is reported occurring in gyrotropic quantum wells in the presence of a magnetic field. The effect is caused by spin-orbit interaction and may be observed even for unpolarized radiation. The current occurs for particular relative orientation between magnetic field, current and crystallographic orientation.
