Resumen

We report on calorimetric, resistivity, and magnetization measurements on single crystal BaIrO3 and its derivatives. All results indicate a phase transition at T_c=175 K, and two additional features are observed in resistivity: a sharp peak at 80 K and an upturn at 26 K. It is found that dilute impurity doping with Sr drastically suppresses T_c and leads to an instant nonmetal to metal transition below T_c, underlining the instability of the ground state.
