Positive temperature coefficient of the thermal conductivity above room temperature in a perovskite cobaltite

The thermal conductivity above room temperature is investigated for LaCoO(3)-based materials showing spin-state and insulator-metal crossovers. A positive temperature coefficient (PTC) of the thermal conductivity is observed during the insulator-metal crossover around 500 K. Our analysis indicates t...
