Magnetic properties of two new classes of highly p-type doped II–VI diluted magnetic semiconductors (DMS): thin layers of Be_1—xMn_xTe:N and bulk Zn_1—xMn_xTe:P are presented. Despite the fact that the samples are insulating, we observe clear indications of the low temperature ferromagnetic correlation, namely: (i) positive Curie-Weiss temperature (T_CW ≈ 2 K), and (ii) open hysteresis loops at temperatures below T_CW. A qualitative analysis of the results favours those models of the carrier-mediated ferromagnetism in DMS which allow for the coupling of only a part of the available spins.
