- Dear Prof. Ozaki
I use OpenMX-3.0 to calculate the DOS of hcp Gd with LSDA-CA. The calculated spin-up 4f peak is at about -9eV while the spin-down 4f peak at about +5eV. This result is similar to the results given by other codes such as LMTO, FPLAPW using LDA+U (Ueff=6-7eV). I wonder if the primitive PAOs have considered the on-site 4f electron correlation for Gd and other rare earth element, or sth wrong with my input file.
Best Regards,
xubo
