Abstract

We report on the observation of both the 80- and 110-K superconducting transitions in a nominally BiSrCaCu2Ox material produced by a new chemical synthesis procedure as well as by solidstate reaction. We also discuss a method for the confirmation of the presence of superconductivity when only a small amount is present.
