Intrinsic photoinduced anomalous Hall effect

We have measured the intrinsic photoinduced anomalous Hall effect (PI-AHE) in very high mobility two-dimensional hole gases. In this new effect, similarly to both the spin and anomalous Hall effects, carriers with different spins are deflected to opposite sides of the sample by the spin–orbit interaction, thereby producing in this case a photoinduced voltage transverse to the applied current. We have been able to measure the intrinsic PI-AHE in finite magnetic field in symmetrically and asymmetrically doped (3 1 1)-grown quantum wells but not in (1 0 0)-grown wells.
