中文摘要 | The structure and transport properties of the V-doped La2-xSrxCuO4+delta system have been studied in this paper. The maximum doping concentration of V for Cu is 0.15 and a tetragonal-to-orthorhombic phase transition occurs at x = 0.10. Resistivity and magnetization measurements show that the V doping will depress the superconductivity in this system. The Kondo-like effect gives a good description of the temperature dependence of resistivity for all samples. The superconducting transition temperature T-c systematically shifts to lower temperature with increasing V concentration and disappears at a critical concentration x(c) = 0.15. This x(c) is much higher than that of the La1.85Sr0.15Cu1-xMxO4+delta (M = Fe, Co, Ni, Zn, Mg, Al and Ga) systems, in which Tc disappears when x = 0.018-0.04. A possible explanation for this phenomenon is presented. In addition, there exists a small concave section in the T-c-x phase diagram around x = 0.02, very similar to the 1/8 behaviour in the La2-xSrxCuO4 system. |
