How to calculate the magnetic anisotropy energy using the VASP code?

I want to calculate the magnetic anisotropy energy of the CrI$$_3$$ monolayer which has 8 atoms per unit cell. I have understood from VASPWIKI that there are two steps:

1. A standard SCF collinear calculation is used to generate the WAVECAR and CHGCAR files.

2. A non-collinear calculation by adding these tags: LSORBIT = .TRUE. ,ICHARG = 11, LMAXMIX = 4 and SAXIS.

I also understand that step 2 must be run three times with: SAXIS=0 0 1, SAXIS=0 1 0 and SAXIS=1 0 0. But I didn't understand how to set the MAGMOM tag in the second step. Knowing that in the first step I specified MAGMOM = 2*5.0 6*0.6 because I have 8 atoms (two are magnetic and six are non-magnetic).

Could you please help me in choosing the right setting of the MAGMOM tag?

You don't need to set the MAGMOM tag in the second step.
This is because the charge density (including the spin density which is the charge difference between spin-up and spin-down) is read in from CHGCAR and kept constant throughout the calculation due to ICHARG = 11.
