(color online) The illustration of p–d repulsion model in Zn_1−xMn_xTe. (I) Atomic magnetically polarized energy levels of Mn cation and host lattice Te anion, (II) exchange splitting of the energy levels Δ_x(d), (III) further splitting of the Mn-3d energy levels due to the crystal field, (VI) p−d exchange splitting Δ_x(p−d), due to the interaction between Mn-3d and Te-5p energy levels, the shaded area shows host lattice valence and conduction band. The figure description is followed by the reference.^[59]
