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.
