Fig. 2. (Color online) Evolution from LS coupling (JHλ = 0) to JJ coupling of t2g4 (λJH = 0) as R=1JHJH+λ increases. (a) Concentation of the hole excitations from t2g5 to t2g4, (b) Energy levels of t2g4 energy eigenstates. The line colors represent the excitation character of the corresponding hole excitation jeff = 1/2 (jeff = 3/2) as blue (red), respectively.
