# External magnetic field in VASP?

I have never found any tags or documentation regarding external magnetic field in VASP but in different well known published articles$$^1$$, the implementation of the external magnetic field by VASP has been discussed.

Can anyone please explain how is it possible to simulate the external magnetic field in VASP?

• +1. We also have a VASP chatroom, could you drop by and say hello at least once? chat.stackexchange.com/rooms/109983/vasp – Nike Dattani Aug 29 '20 at 20:37
• EFIELD has been implemented since at least 4.6. Now you just have to sort out which direction. – Bituoso Aug 31 '20 at 3:20
