Abstract
With the objective of exploring the unknown thermodynamic phase diagram of Bi1-xSrxMnO3 family, we present here an investigation of the temperature-dependent (10K < T < 900K) thermodynamic behavior of Bi1-xSrxMnO3 (x=0.25, 0.30, 0.50). We report here probably for the first time the thermal expansion and specific heat along with other thermal properties of strontium doped perovskite manganite BiMnO3. The specific heat values revealed by using RIM are in closer agreement with the available experimental data for some concentrations (x) of Bi1-xSrxMnO3. In addition, the results on the cohesive energy (f) in orthorhombic perovskite phase, molecular force constant (¦), Reststrahlen frequency (no) and Gruneisen parameter (g) are also presented.
