Abstract T 6 → T 8 , magnetoabsorption spectra of semimetallic Hg 1−k Mn k Te alloys ( k ≦ 2%) provide evidence of striking modifications in the “spin” states of the T 8 Landau levels, in particular a drastic increase of the electronic Lande factor is observed. These anomalous spin effects are interpreted as the manifestation of the exchange interactions between the mobile electrons and the d electrons localized on the Mn atoms. The exchange integral for T 8 levels is estimated.
