The temperature dependence of the paramagnetic susceptibility of the compounds Cdi.xGaxCr2S4, CdCr2S4.y, and CuCr2S4.y were investigated. It was observed that the paramagnetic Curie point is lowered with increasing doping level. It is suggested that this phenomenon is due to the presence of antiferron states of the donor electrons.
