La and Sm Co-doped SrTiO 3- δ Thermoelectric Ceramics

Superconductivity of SrTiO 3 − δ

Superconducting SrTiO 3−δ was obtained by annealing single crystalline SrTiO3 samples in ultra high vacuum. An analysis of the V (I) characteristics revealed very small critical currents Ic which can be traced back to a unavoidable doping inhomogeneity. R(T) curves were measured for a range of magnetic fields B at I ≪ Ic, thereby probing only the sample regions with highest doping level. The re...

Synthesis and Thermoelectric Behavior in Nanoparticles of Doped Co Ferrites

Samples of CoFe2-xCrxO4 where x varies from 0.0 to 0.5 were prepared by co-precipitation route. These samples were sintered at 750°C for 2 hours. These particles were characterized by X-ray diffraction (XRD) at room temperature. The FCC spinel structure was confirmed by XRD patterns of the samples. The crystallite sizes of these particles were calculated from the most intense peak by Scherrer f...
