I have tried to calculate the linear response using LDAUTYPE = 3. However, the f electron in NSC calculation didn't respond to the U you chosen, only the d electron is responding. The NSC calculation started with reading the charge file from DFT with U=0.
INCAR
Code: Select all
PREC = A
ENCUT = 500.0
EDIFF = 1E-6
EDIFFG = -1E-2
ISMEAR = 0
SIGMA = 0.2
LMAXMIX = 6
ISPIN = 2
MAGMOM = 2 -2 2 -2 8*0
LORBIT = 11
NCORE = 24
ICHARG = 11
LDAU = .TRUE.
LDAUTYPE = 3
LDAUL = 2 -1 -1
LDAUU = 0.05 0.00 0.00
LDAUJ = 0.05 0.00 0.00
Is there anything I need to take care about for the f electron besides of the LMAXMIX?

I would say that the issue is that you are only setting the U interaction for the l=2 orbital of the first ionic type:
In order to add the interaction you need to set:
