Abstract
We report on calorimetric, resistivity, and magnetization measurements on single crystal BalrO
3 and its
derivatives. All results indicate a phase transition at
=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
and leads to an instant nonmetal to metal transition below
underlining the instability of the ground
state.
