| 中文摘要 | By using chelating-coprecipitation method, Zn is uniformly doped into the La2-xSrxCu1-yZnyO4 system. When y = 0.025, it is found that the highest superconducting transition temperature shifts to about x = 0.19. Furthermore, the low-temperature normal state resistive data show that the point x = 0.19 separates the electronic phase diagram into two regions: the normal state shows an insulating behavior when x < 0.19, and a metallic behavior when x > 0.19. We attribute the shift of the optimal doping point and the metal-insulator transition at x = 0.19 to the localization of the charge carriers induced by the Zn impurities. (C) 2004 Elsevier B.V.
