|Title:||EVIDENCE OF SURFACE SUPERCONDUCTIVITY IN THE HIGH-TC OXIDES|
|Abstract:||For the first time evidence of surface superconductivity in the high-Tc superconductors is shown here. The rounded portion of the magnetization vs. temperature curves near the transition onset is interpreted as a universal response exhibited by any granular superconducting sample. A clear criterion to locate Hc2, and Hc3, is presented, together with a preliminary discussion of the consequences implied by these basic facts.|
