[Pw_forum] Fe pseudopotential

HI,

Sorry I don't know. But as far as I know, when I get a new pseudo the first step is to  reproduce the 
lattice parameters for simple substance, and then the compond you care about, such as FeO et al.
And during the test procedure I will change the cutoff of pesudo to see whether the calculated energetic
parameters such as energy, force et al. and the geometric parameter, such as a, b, c, or alpha, beta,gamma
is converged.

NOTE, all above is a view of a beginner. don't trast me without considering.

Dear Vega
Its pseudo wave functions are similar all electron wave functions for Fe atom (without any nodes)
and its energy is near all electron energies .Isn't it enough?
(I'll test it for Fe as you said)

Thanks for you attention

I think you can run a simulation with Fe lattice using different cutoff. and check the lattice parametters with the 
experimental data and the DFT calculation done by others in the literature.

Dear all

I need Fe pseudopotential for Born-Oppenhiemer molecular dynamics .I built it by  input and ld1.x

 that I attached with this mail but I'm not sure that psudopotential is correct or not?

Thanks
