We have studied systematically the effects of a Pb layer on the superconductivity of Bi-Ca-Sr-Cu-O films. The Bi-Ca-Sr-Cu-O films were prepared by RF magnetron sputtering ~F.om\_ a sintered\_ceramic target. The sputterinB was performed at room temperature. The ~nlcKness or PD-iayer varies Trom sever
Pb-doped Bi-Sr-Ca-Cu high-To superconducting oxides have been prepared by a modified sol-gel process via the EDTA route. Upon decomposing the X-ray photoemission spectrum of the Cu 2pa/2 core level of the superconducting oxide into three components Cu ~+, Cu 2 + and Cu 3+, we have found an obvious t
