We investigate the spin-transfer torque in a magnetic multilayer structure bymeans of a spin-diffusion model. The torque in the considered system,consisting of two magnetic layers separated by a conducting layer, is caused bya perpendicular-to-plane current. We compute the strength of the field-like andthe damping-like torque for different material parameters and geometries. Ourstudies suggest that the field-like torque highly depends on the exchangecoupling strength of the itinerant electrons with the magnetization both in thepinned and the free layer. While a low coupling leads to very high field-liketorques, a high coupling leads to low or even negative field-like torques. Thedependence of the different torque terms on system parameters is consideredvery important for the development of applications such as STT MRAM andspin-torque oscillators.
