For the Non-magnetic case, the convergence for the SCF calculation has been achieved using 8000 k points while for the AFM case, it is not convergent at all using 4096 k points after 100 iterations. The charge and energy keep fluctuating. However, for GdPtBi with the same lattice structure and AFM order, the corresponding calculations are convergent. I felt very confused.
