Thermal diffusivity and conductivity of La 0.7Ca 0.3-xSr xMnO 3 (x= 0 to 0.10)
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...

| description | 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. Phonon was the dominant contributor to thermal conductivity and the electronic contribution was less than 1%. Enhancement of electrical conductivity ? and thermal diffusivity for x ? 0.08 was observed in both series of samples. The grain size of the samples (28 to 46 ?m) does not show any affect on the thermal and electrical properties. � (2012) Trans Tech Publications. |
