Spin current calculation

[karn]

Hello,

I would like to obtain in total 4 plots, as mentioned below, at different biases for a two terminal structure(FM-Semiconductor-FM).
(1)spin up current in parallel config
(2)spin down current in parallel config
(3)spin up current in anti-parallel config
(4)spin down current in anti-parallel config

I am not sure what is the exact procedure to achieve these results so please advise me on how to set about getting these plots. Any help in this regard will be appreciated.

First of all, thanks for replying. Now I have gone through this tutorial very carefully(How could i have not?) but i don't see spin current VS voltages plot anywhere in it. All that is calculated in that tutorial is Transmission co-efficient at different K values. This spin current vs bias voltage plot is imperative for me. So i would really appreciate if you could explain that in a little bit detail. Have a nice day..!!
