ISPIN = 1 | 2
Default: ISPIN = 1 

Description: ISPIN specifies spin polarization.


  • ISPIN=1: non-spin-polarized calculations are performed.
  • ISPIN=2: spin-polarized calculations (collinear) are performed.

By combining ISPIN with MAGMOM collinear magnetism can be studied.

Important: For noncollinear calculations ISPIN is ignored. In VASP 6.5.0, the calculation will exit with an error message if ISPIN=2 and MAGMOM is used in combination with the LNONCOLLINEAR=.TRUE.
