PM-FM transition in a DE model
arXiv:cond-mat/0506528 · doi:10.1016/j.physb.2006.01.009
Abstract
We study paramagnetic - ferromagnetic transition due to exchange interaction between classical localized magnetic moments and conduction electrons. By solving the Dynamical Mean Field Approximation equations we find explicit formula for the transition temperature for arbitrary electron dispersion law, concentration and re lation between exchange coupling and the electron band width. We present the results of calculations of the for the semi-circular electron density of states.
