Spin Accumulation

Spin transport and distribution of spin accumulation in CuPt/Fe heterostructure are numerically investigated, using linearized Levy-Fert model. It was shown that Spin Hall Effect in CuPt layer produces non-equilibrium spin accumulation in adjacent ferromagnetic layer. Spin accumulation vector is not collinear with the direction of magnetization in ferromagnetic layer which leads to the appearance of spin transfer torque. The absolute values and angular dependence of this torque were calculated and it was demonstrated that for the current the values of torques are sufficient for manipulation of magnetization of ferromagnetic layer.

A useful interpretation of the spin-accumulation and spin-current distributions in magnetic nanostructures with diffusive transfer has been discussed. A mathematically equivalent mechanical system was proposed that provides an intuitive understanding of the dependence of the spin-transfer torque values on various parameters. In particular, it gives a clear explanation for the sign change of the spin-transfer torque in asymmetric F/N/F structures.
