epw for ferromagnetic system

[inoka]

Dear Developers

I need to get the relaxation time of a ferromagnetic system. But when I use nspin=2 with starting_magnetization in the scf.in and nscf.in, the code complains with the error below.

from epw_readin : error # 1
El-ph and spin not implemented


So could you please let me know if there is other way to do this?

Thank you in advance

Dear Inoka,

Unfortunately as you saw EPW does not work for magnetic systems. I believe it is implemented in the PHonon code - even if the summary in the header of phonon.f90 says differently - and if so we should look into implementing it in EPW in the near future.

Best,
Carla

Dear Dr. Carla

Thank you very much for your reply.

Yes. I think it is great if it is possible to do that. Because I know this EPW code is the only way to get the relaxation time of a system. And mostly for metallic compounds we need to add metallic behavior.

I kindly request from you to add this feature to EPW.

Thank you
Inoka

Dear Inoka,

I got this same error while calculating the resistivity of my system. Did you find a solution? As i see your post is quite old.



Thanks.
Ahmad.

Dear Ahmad:

EPW still doesn't support the case of nspin=2.
