By considering the excitation of the spin wave at the interface between magnetic electrodes and insulating barrier and 3r2 Ε½ . taking the mean-field approximation to the s-d exchange interaction, a T law is derived for the temperature T dependence of the exchange field in ferromagnets. Then we have
