摘要

We present a theory to model carrier mediated ferromagnetism in concentratedor diluted local moment systems. The electronic subsystem of the Kondo latticemodel is described by a combined equation of motion / coherent potentialapproximation method. Doing this we can calculate the free energy of the systemand its minimum according to the magnetization of the local moments. Thus alsothe Curie temperature can be determined and its dependence on important modelparameters. We get qualitative agreement with the Curie temperatures'experimental values of Ga$_{1-x}$Mn$_x$As for a proper hole density.
