  • Initialization of moment along z-direction (out of plane) (MAGMOM = 0.0 0.0 1.0).
  • Spin-orbit interaction switched on (LSORBIT=.TRUE.).
  • For the second calculation, switch to in-plane magnetization by setting MAGMOM = 1.0 0.0 0.0 in the INCAR file.

Calculation

The sample output for the total energy using out of plane magnetization is given in the OSZICAR file:

...
DAV:  20    -0.371322930070E+01    0.15852E-03   -0.11632E-03   636   0.235E-01    0.225E-02

   1 F= -.37132320E+01 E0= -.37139803E+01  d E =0.224478E-02  mag=  0.0000  0.0000  0.9035

The sample output for the total energy using in plane magnetization looks like the following:

...
DAV:  19    -0.371443443024E+01   -0.80757E-04   -0.35822E-03  1084   0.323E-01    0.119E-02
