arXiv:1612.04696 · doi:10.1103/PhysRevB.95.054503
Abstract
We consider charge transport properties in realistic, fabricable, Ferromagnet/Superconductor spin valves having a layered structure , where and denote the ferromagnets, the superconductor, and the normal metal spacer usually inserted in actual devices. Our calculation is fully self-consistent, as required to ensure that conservation laws are satisfied. We include the effects of scattering at all the interfaces. We obtain results for the device conductance , as a function of bias voltage, for all values of the angle between the magnetizations of the and layers and a range of realistic values for the material and geometrical parameters in the sample. We discuss, in the context of our results for , the relative influence of all parameters on the spin valve properties. We study also the spin current and the corresponding spin transfer torque in structures.
