Spin‐orbit interactions and dynamical Jahn–Teller effect in the 4E states of Mn2+ in cubic and nearly cubic symmetry

摘要: A very detailed analysis of the fine structure 4E(G) state Mn2+ in cubic and nearly clusters is presented to account for unusual observed ZnSe:Mn. First, experimental results are reported which show that spin‐orbit interaction ZnSe about one half previously or as MnS4, MnBr4, MnCl4 Γ8 neatly shifted with respect Kramers doublets Γ6 Γ7. Second, a model elaborated shows second‐order interactions reduced by Jahn–Teller coupling E vibrational modes accounts well overall splitting studied fourth‐order correctly describe shifts state. The validity perturbation schemes discussed compared those obtained from complete diagonalization d5 configuration.
