Figure 15
Energy diagrams illustrating the splitting of the ground state of a d6 Fe2+ ion. (a) As a function of the octahedral crystal field 10Dq parameter with the spin–orbit coupling (ξ) and magnetic exchange interaction (Jexch) set to zero. (b) As a function of Jexch with 10Dq = 1.25 eV and ξ = 0. (c) As a function of ξ with Jexch = 90 meV and 10Dq = 1.25 eV. |
