| 中文摘要 | A first-principles method is developed to study the spin transfer torques in magnetic noncollinear textured ferromagnet-superconductor heterostructure. We apply the method to study the long-range spin-triplet pairing (S(z) = +/- 1) induced by the spin-flip scattering near the ferromagnet-superconductor interface. The long-range spin-triplet Andreev reflection will saturate to the same value as usual Andreev reflection with strong enough spin-flip scattering. We find that the giant magnetoresistance effect of a spin valve with a superconductor contact can be restored by a small amount of interfacial spin-flip scattering. |
