Abstract EN
Polycrystalline samples of Ca1−xGdxMnO3−δ (x=0.00, 0.02, and 0.05) have been studied by X-ray diffraction (XRD), electrical resistivity (ρ), thermoelectric power (S), and thermal conductivity (κ).
All the samples were single phase with an orthorhombic structure.
The Seebeck coefficient of all the samples was negative, indicating that the predominant carriers are electrons over the entire temperature range.
The iodometric titration measurements indicate that the electrical resistivity of Ca1−xGdxMnO3−δ correlated well with the average valence of Mnv+ and oxygen deficiency.
Among the doped samples, Ca0.98Gd0.02MnO3−δ had the highest dimensionless figure of merit 0.018 at 300 K, representing an improvement of about 125% with respect to the undoped GaMnO3−δ sample at the same temperature.
