The magnetization versus magnetic field in Zno 95Mno o5Te has been measured at 1.6 K in a pulsed high magnetic field up to 42 T. The first, second, and the beginning of the third magnetization step corresponding to the nearest-neighbor (NN) manganese-ion-pair magnetization are observed. The analysis of the data in the framework of a generalized cluster model leads to three main results: (i) the exchange constant between NN Mn ions is J/k& ---8. 8+0. 1 K; (ii) the contribution of three Mn ion clusters becomes non-negligible for magnetic fields higher than 20 T; (iii) the results support a random distribution of Mn ions.
