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. |
