We report the room temperature thermal conductivity ? and thermal diffusivity ? of polycrystalline La 0.7Ca 0.3-xSr xMnO 3 for x = 0 to 0.1. The samples were prepared by heating at 1220 and 1320�C. The insulator-metal transition temperature, T IM and thermal diffusivity increased with Sr content. Ph...
