[Pw_forum] Phonon calculation of magnetic system

[Stefano Baroni]

Sounds like a weird question: "is it necessary to be more accurate, rather than less?"
DFPT in magnetic systems has been implemented by A. Dal Corso including standard LSDA/GGA and spin-orbit interactions.
I've heard somebody has been working on DFPT+U, but I am not sure of the status of the project
This being said, you better answer your question, when and where you can: just do a few sample calculations including and excluding magnetic interactions and judge by yourself what is best ...
