Optical polarons in semi-magnetic semiconductors

The solution of problem about anisotropic bulk optical polaron is generalized for the case of weak coupling in one valley cubic crystal structure. Then on basis of obtained results expressions for the ground state energy and polaron mass of the electron are given in the SMSC with an anisotropic energy spectrum. Based on obtained calculations it is found that the transverse and longitudinal polaron mass, renormalized due to electron-phonon interaction, increases compared with corresponding band values. However, polaron mass of electrons decreases owing to exchange interaction with increasing magnetic field
