Optically Induced Magnetization of CdMnTe Self-Assembled Quantum Dots
arXiv:cond-mat/0403298 · doi:10.1063/1.1723694
Abstract
We demonstrate that resonant excitation of CdMnTe self-assembled quantum dots creates an ensemble of spin-polarized magnetic polarons at B=0 T. The strong spatial confinement characteristic of quantum dots significantly increases the stability of magnetic polarons so that the optically induced spin alignment is observed for temperatures > 120 K.
