It was found that partially Fe-substituted Ba cobaltite, BaCo0.7Fe0.3O3-δ, shows sharp PTC behavior at temperature above 850 °C. As revealed by XRD measurements, the PTC behavior is accompanied by phase transformation between hexagonal perovskite structure (low temperature) and cubic one (high temperature).
