In getting IV curve for my two probe device i noticed it included all spin. can i get separate current for spin up and spin down.

For a non-polarized system the up-spin and the down-spin components are identical....So, in your Transmission spectrum Analysis...if you calculate, say the up-component of the transmission spectrum only.....then the Current calculation done on the values of the transmission data...will give you the required result.... But make sure, that the expression of current has not got multiplied by 2 again, to consider both the spin components.....
