The solid solution between ferromagnetic MnSb and paramagnetic NiSb, MnxNi1−xSb (0≤x≤1.0), with NiAs structure was synthesized in high pressure and high temperature atmospheres. The decomposition temperature was determined to be 420∼480 K. The critical concentration of ferromagnetism was obtained to be xc=0.65 at absolute zero. A new type spin glass state with double transition points, Tsg1 and Tsg2, was found in a wide range of 0.2≤x≤0.65 in the paramagnetic phase. The maximum transition point was estimated to be Tsg1=60 K and Tsg2=190 K. The electrical resistivity showed no anomaly corresponding to Tsg1 and Tsg2, and the temperature dependence in the spin glass state was given to be T2 and T3⁄2 at lower temperature. Some discussions are given for the experimental results.
