Abstract :
We report on microwave (mw) radiation induced electric currents in semimagnetic CdMnTe and nonmagnetic InAs: Si quantum wells subjected to an external in-plane magnetic field. The current generation is attributed to the spin-dependent energy relaxation of electrons heated by mw radiation.
