AFM and magnetic constraint

#1 Post by chandani_nandadasa1 » Sun Mar 29, 2020 8:55 pm

Dear vasp-community,

I have to constraint the direction of the magnetic moment of an AFM structure as here. I need to flip the first atom from 0 0 1 to 0 0 -1.
I_CONSTRAINED_M = 1
M_CONSTR = 0 0 -1 0 0 1
MAGMOM = 0 0 3 0 0 3

The structure is going back to FM after a non-collinear calculation. The constraint didn't work. Could anyone tell me why?

Thanks
