Abstract
AbstractWe demonstrate a method to electrically control the spin polarization in a diluted magnetic semiconductor (DMS) quantum well (QW) on a micrometer length scale. A variable magnetic field generated from a microscale current loop atop a single CdMnTe/CdMgTe QW magnetizes the Mn2+ ion spins in the DMS QW and, via the sp–d exchange interaction, polarizes the spins of photon‐generated carriers. In the absence of an external field, the spin polarization can be switched on a time scale clearly below 1 ns.
