The temperature dependence of electrical resistance in the system (Cr_xMn_<1-x>)Sb was studied, which forms a homogeneous nickel-arsenide type solid solution of ferromagnetic MnSb and antiferromagnetic CrSb over the whole concentration range. It has been found that the resistance increases with rising temperature until it reaches a maximum at the Curie or the Neel point, and then it decreases. For the compounds with chromium concentration of 0.7〓x〓0.8, another type of anomaly, that is, a small discontinuity of the resistance curve was observed at low temperatures. It is concluded that this anomaly may be attributed to the magnetic transition between ferromagnetic and antiferromagnetic states, which was previously proposed to exist in this range of x.
