We report on microwave (mw) radiation induced electric currents in (Cd, Mn)Te/(Cd, Mg) Te and InAs/(In, Ga)As 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. The relaxation produces equal and oppositely directed electron flows in the spin-up and spin-down subbands yielding a pure spin current. The Zeeman splitting of the subbands in the magnetic field leads to the conversion of the spin flow into a spin-polarized electric current. (c) 2010 American Institute of Physics.
