AbstractWe report magnetic properties of [Ca2CoO3-δ]0.62CoO2 (Ca349) powders with various average size and the Bi- and Sr-doping effects on thermoelectric properties for the magnetically grain-aligned and densified Ca349 thick films. Magnetic anisotropy at 300 K depended on the initial average size of Ca349 powders and decreased with the decrease in the size. This presumably suggests that distortion of crystal structure was induced by a ball-milling process and led to the change of magnetic anisotropy. On the Bi- and Sr-doping effects, an obvious enhancement of thermoelectric properties did not emerge in the case of the Sr-doping, whereas the enhancement was observed for the Bi-doped Ca349 thick films. However, a drastic decrease of magnetic anisotropy was caused by the Bi-doping. For usage of the p-type layer in multilayered thermoelectric module, tuning of the Bi-doping levels in which both enhancement of thermoelectric properties and a certain level of magnetic anisotropy are achieved is required.

We have studied the doping effects of the electronic structure of Sr 1−x La x TiO 3 for x=0, 0.25, 0.5, 0.75, 1, using the Tight-Binding Linearized Muffin Tin Orbitals (TB-LMTO) method. The calculated energy gap of SrTiO 3(x=0) shows an excellent agreement with the experimental result. The system goes to metallic phase for 0<x<0.95 and goes to an antiferromagnetic phase for x=1, agreeing well with the experimental observations. The cohesive energies for the above mentioned x values are also calculated.
