Abstract
A theory of localized magnetic polarons in diluted magnetic semiconduc tors is developed. The theory involves below band gap states and alloy fluctuations utilizing the optimal fluctuation method. A comparison o f the theoretical calculations with published experimental results is performed. The implications of the comparison are discussed and the ne ed for extending the theory to include an additional impurity/native l attice defect potential described. The magnetic field and temperature dependence of the polaron energies are also evaluated. (C) 1997 Americ an Institute of Physics.
