  • Initial magnetic moments of 2μB (Ni) and 0μB (O).
  • AMIX=0.2 and AMIX_MAG=0.8 (default), BMIX and BMIX_MAG practically zero, i.e. linear mixing.

Calculation

The total magnetic moment should be 0 in the OSZICAR file:

DAV:  13    -0.267936242334E+02    0.12794E-03   -0.12638E-04   552   0.298E-01    0.169E-02

   1 F= -.26793635E+02 E0= -.26793635E+02  d E =0.000000E+00  mag=     0.0000

The partial and integrated magnetic moments within the PAW spheres are given in the OUTCAR file:
