| 中文摘要 | Structural, electrical transport, and magnetic properties of polycrystalline samples of PrBa2-xSrxCu3O7-delta were investigated. The solid solubility limit for Sr in PTBa2-xSrxCu3O7-delta was found to be about 0.8 and the orthorhombic-to-tetragonal phase transition occurred at x=0.2. With Sr doping, the electrical resistivity reduced abruptly, especially at low temperatures. For the x=0 sample, rho(20 K)/rho(300 K)similar to 10(4), for the x=0.8 sample, rho(20 K)/rho(300 K)similar to 100, while for x=1, rho(20 K)/rho(300 K)similar to 3. In contrast to the aforementioned change, the antiferromagnetic ordering temperature T-N and the effective magnetic moment of Pr ions showed no obvious change indicating their insensitivity to Sr doping. The results are discussed considering the Sr doping induced variation of hybridization between Pr ions and O-2p of the CuO2 planes. |
