Abstract The ion implantation method was used to synthesize Zn 1— x Ni x Te films. Magnetic circular dichroism and magnetoabsorption spectra were measured in a sample of nominally x = 0.017. They reveal a substantial Zeeman splitting (up to ≈2.3 meV) of the E 0 transition. The temperature and field dependences of the Zeeman splitting are analyzed within a previously developed theoretical model for the hybridization‐induced sp–d interaction, which includes the orbital degrees of freedom. The results indicate the presence of a static Jahn‐Teller distortion and suggest a valence band sp–d exchange parameter value ≈—1 eV.
