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
## Abstract Doubleβbarrier magnetic tunnel junctions (DMTJs) with and without an amorphous ferromagnetic material such as CoFeSiB 10, CoFe 5/CoFeSiB 5, and CoFe 10 (nm) were prepared and compared to investigate the bias voltage dependence of the tunneling magnetoresistance (TMR) ratio. Typical DMTJ
