Abstract: The structure, magnetic and electrical properties of MnTe1-xSbx (x = 0, 0.1, 0.15, 0.2 and 0.25) alloys have been investigated. The MnTe1-xSbx compounds crystallize in hexagonal NiAs - type structure, and impurity MnSb phase appears when x ≧0.15. MnTe0.9Sb0.1 alloy exhibits ferromagnetic behavior at 350 K. The anomaly of resistance of the MnTe0.9Sb0.1 alloy is observed around 300 K. A peak appears around 304 K in the temperature dependence of the specific heat of all the MnTe1-xSbx (x = 0.1, 0.2 and 0.25) alloys. A plausible explanation is given for the anomaly of resistivity and the peak of specific heat of the MnTe0.9Sb0.1 alloy.
