Abstract
H(c2)(T) has been measured for thin BSCO films over a larger combined range of magnetic field and reduced temperature than for any other sup erconductor. H(c2)(T) diverged anomalously as the temperature decrease d: At the lowest temperature, it was 5 times that expected for a conve ntional superconductor. Such a strong divergence cannot be explained b y any conventional model.
