Electrical conduction and thermal properties of Bi-doped Pr0.7Sr0.3MnO3 manganite
Mamatha D Daivajna Neeraj Kumar Bhasker Gahtori V P S Awana Y K Kuo Ashok Rao
Electrical and thermal properties of Bi-doped Pr0.7Sr0.3MnO3 (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 (𝑇MI, 𝑇C, 𝑇CP). Thermo-power measurements further strengthen our conclusion for the presence of magnetic polaron, generated due to hybridization of Bi3+–6s2 and O2-–2𝑝 orbital and polaronic conduction mechanism.
