Magnetic susceptibility of semimagnetic semiconductor Zn 1‐x Mn x S (x = 0.05, 0.10) is measured by the Faraday method. Starting from the isolated cluster model in the nearest‐neighbour approximation, and from the random distribution of Mn 2+ ions, the temperature dependence is calculated of the magnetic susceptibility of Zn 1‐x Mn x S. By comparing these results with experimental χ (T) data, good agreement is obtained only for lower concentration x = 0.05. Treating the probabilities of finding the Mn 2+ ions as singles, pairs, or triplets as adjustable parameters (modified distribution), quantitative agreement is obtained for both concentrations. Probabilities for every type of cluster, in both distributions, are given. The results show an enhancement of the clusterisation when the concentration x increases.
