[QE-users] 答复: Magnetic moment and Spin polarization in cp.x

[Giuseppe Mattioli]

No, it is a little more complex. AFAIK, you can perform  
spin-unrestricted fixed-occupation MD simulations (no smearing), or  
ensemble-DFT simulations. There are limitations in the latter case  
(BOMD only, CG diaginalization, ...), but I cannot provide further  
information because I've never used it. Flick through  
CPV/examples/example08 for details
