Photoluminescence (PL) spectra near the fundamental absorption edge are investigated in Cd1-xMnxTe (x = 0.03 to 0.3) at 4.2 K in magnetic fields up to 23 T for Faraday configuration. For PL of free excitons and neutral-donor(acceptor)-bound-exciton transitions in low concentration of Mn (x = 0.03 and 0.05), diamagnetic shifts are observed in the region of high magnetic fields. In the case of x = 0.1 and 0.3 the decrease in energy of these PL peaks is observed in the region of high magnetic fields with increasing magnetic fields corresponding to magnetization steps and large phenomenological temperature T0 describing spin interaction. We determine exchange integrals and T0 using the magnetic field dependence of PL peaks. For x ≤ 0.1 PL spectra of self-trapped magnetic polaron are observed but they disappear at low magnetic fields as ∼1 T.
