Title: Transport properties of (Ca{sub 1−x}Sr{sub x})Mn{sub 0.95}Sb{sub 0.05}O{sub 3} perovskites

The transport properties as a function of composition and temperature of (Ca{sub 1−x}Srx)Mn{sub 0.95}Sb0.{sub 05}O{sub 3} perovskite compounds have been investigated for the first time using extended rigid ion model (ERIM). (Ca{sub 1−x}Srx)Mn{sub 0.95}Sb0.{sub 05}O{sub 3} (x = 0.0, 0.10, 0.15 and 0.17) exhibit a single phase with an orthorhombic perovskite structure (Pnma). Furthermore, to understand better the thermodynamical properties of the present system, ERIM is developed and applied to study the specific heat for these compounds over a wide range of temperature. The trends of variation of computed thermodynamical and transport properties have shown remarkable good agreement with corresponding experimental data.
