I am trying to set up calculations to model antiferromagnetic UO2.
I have tried settingg:
MAGMOM = 1*2 2*-2 1*2 8*0
however in the OSZICAR output mag = 0 and I believe it should be in the region of 2.
I have also tried using the NUPDOWN = 2 - which has no effect.


Any help would be much appreciated

Hi,

Is this a bulk structure ?? If that s a bulk the total magnetic moment should be zero, because UO2 is AFM and so, the total magnetic moment below the Neel temperature is zero.

If your are modelling a surface, our total initial mag mom is zero. I m not sure about the UO2 but for Co3O4 which is AFM, the total magnetic moment of a surface structure is not zero


Cheers
