摘要：

We have investigated the magnetic and electronic transport properties in the single crystals of La1-xPrxCoO3 System. The signs of the thermoelectric power and the Hall coefficient change from positive to negative by the 10% Pr-doping in LaCoO3, and they change from negative to positive by 10% La-doping in PrCoO3. These results imply that the sign of the carrier of the system changes through the hybridization between Pr(4f) and O(2p(n)) orbitals depending on the Pr concentration.
