Abstract

Electrical and thermal properties of Bi-doped Pr _0·7Sr_0·3MnO₃ (PSMO) compounds are reported here. It is observed that Bi-doped PSMO compounds follow variable range conduction mechanism. Specific heat, thermal conductivity and thermo-power measurements show that larger Bi-ion, in place of smaller Pr ion, enhances their transition temperatures (T_MI, T_C, T_CP). Thermo-power measurements further strengthen our conclusion for the presence of magnetic polaron, generated due to hybridization of Bi³⁺-6s ² and O^2--2p orbital and polaronic conduction mechanism.
