Abstract
A phonon-assisted magnetopolaron effect in diluted magnetic semiconductors is theoretically investigated. It is shown that the binding energy of magne tic polarons can be substantially enhanced if coupling between the magnetic and phonon subsystems is taken into account. In the particular case of "so ft" lattice dynamics, the stability range of the hole-induced magnetic pola ron can be extended to temperatures of a few tens of kelvin and magnetic fi elds of several tesla.
