Abstract

A stable and reproducible superconductivity transition between 80 and 93 K has been unambiguously observed both resistively and magnetically in a new Y-Ba-Cu-O compound system at ambient pressure. An estimated upper critical field ${\mathrm{H}}_{\mathrm{c}2}$(0) between 80 and 180 T was obtained.
