ABINIT Discussion Forums

Dear abinit users,
I am trying to compute the B-H curve for magnetic systems. I found that in an older abinit version (7.0) there was some possibility to impose a finite magnetic field for berry phase calculation but that disappeared in later versions. I also saw the rfmagn keyword in 8.4 version and I was wondering if that could be used. Any help and ideas would be very welcome.
Many thanks,
Robin

Dear Robin,
What you want to do is to apply a magnetic field on your system and see its response? If you want to be restricted to the Zeeman response (spin response and not orbitals) then you have the zeemanfield input variable that allows you to apply a zeeman magnetic field to your system.
Let me know if this is what you wanted.
Best wishes,
Eric

rfmagn is under development - it does not work yet.
