A systematic study on the thermal conductivity, Seebeck coefﬁcient and specific heat of La0.7Ca0.2Sr0.1MnO3:PdO composites is presented. Solid state reaction procedure was employed to synthesis the samples. It is seen from thermal conductivity (κ(T)) studies that the samples exhibit a slope change nature close to their corresponding magnetic phase transition temperature, TC. The overall magnitude of κ is observed to decrease with increasing Pd concentration. The analysis of Seebeck coefficient data, S(T) versus temperature, T was done using Mott's polaron hopping model reveals that the electron-magnon scattering is governing the low temperature region. The temperature dependent specific heat CP(T) is analyzed to determine the entropy change (ΔS) during the magnetic phase transition.
