[Pw_forum] RE : Other Cr pseudopotential options

[BARRETEAU Cyrille]

Thank you Derek for answering faster than me:-)
To be fair, the pseudopotential for Cr and Fe have been mainly developed by my colleague Chu Chun Fu from CEA.
The first paper that you mention was a careful check of the pseudo from an LCAO code (Siesta) and a PW code (QE).
We have later on done a series of calculations on Fe-Cr alloys using these pseudo and were quite satisfied by the result.
	Phys. Rev. B 83, 214103 (2011). 
        Phys. Rev. B 84, 155402 (2011). 
       J. Phys.: Condens. Matter 25 146002 (2013). 

However any pseudo has its own limitation...

Dear Derek,

Thank you, I will email Cyrille and will download and read their paper
and will report back shortly.

All the best,

Ben
