Spin polarized I-V curve plotting

[mbjavan]

Dear ATK users,
How can I plot the I-V curves for both spin up or down states in ATK.13.8 after full IV calulations? it seems that the I-V analyzer show in default state the up spin I-V results . Also it seems the transmission analyzer show in general properties the total current only in different bias voltages.

Thanks

is it possible extracting transmisstion spectra for both spin up and down from transmission analyzer part?
how is it possible extracting from IVcurve calculation I_up and I_down?

For now you are right, these tools only treat the Spin.Sum case. To get the current for a spin component, you can however in a script do

Code: python

t = TransmissionSpectrum(...)
# or read "t" from a file if you have already computed it
#t = nlread("file.nc", TransmissionSpectrum)[-1]
i_up = t.current(spin=Spin.Up)
i_dn = t.current(spin=Spin.Down)
