We developed a microscopic model in order to describe the onset of ferromagnetism (FM) in GaAs:Mn. The proposed kinematic mechanism bears resemblances with the Zener exchange. The calculated Curie temperature for GaAs:Mn is in good agreement with available experimental data of the Curie temperature as a function of the manganese concentration.
