[Pw_forum] Spin-orbital effects and relativistic US-PPs

[Shujun Hu]

Dear Drs,

I want to perform one calculation of Sn-O-Co compound including spin-orbital
effects, which need fully or scalar relativistic US-PPs. But I cannt find the PPs
of above three elements with the same functional, such as PBE or PW91, on the PPs
download webpage. Could you guide me to find such data or transform the non-US-PPs
to the ultrasoft ones?
  Another question, does the spin-orbital effect calculation need all the PPs of
elements to be fully relativistic ones, or scalar relativistic, or partial
elements? If partial are needed, which is more important in the Sn-O-Co compound?

  Best wishes.

                                         Shujun Hu
