| Popis: | We present the calculated low-energy electronic structure, in the meV energy scale, of Sr 2 RuO 4 that is associated with the single-ion states of the Ru 4+ ion. For description of the d electrons of the Ru 4+ ion we take into account the orbital degrees of freedom, the spin–orbit coupling, and the extremely strong d–d electron correlations. These strong correlations lead to the formation of the highly correlated atomic-like 4d 4 electron system. The derived electronic structure is different from that discussed at present in literature. We take recent Raman experimental data as experimental evidence for the existence of the discrete electronic structure. |
