英文摘要	The magnetoexciton polaron (mp) is investigated theoretically in a diluted magnetic semiconductor quantum dot (qd), with the coulomb interaction and the sp-d exchange interaction included. the mp energy decreases rapidly with increasing magnetic field at low magnetic field and saturates at high magnetic field for small qds, and the dependences of the mp energy on magnetic field are quite different for different qd radii due to the different carrier-induced magnetic fields b(mp). the competition between the sp-d exchange interaction and the band gap shrinkage results in there being a maximum exhibited by the mp energy with increasing temperature. our numerical results are in good agreement with experiment (maksimov a a, bacher g, macdonald a, kulakovskii v d, forchel a, becker c r, landwehr g and molenkamp l w 2000 phys. rev. b 62 r7767).
