Abstract

A new compound of the high-temperature ceramic oxide superconductor family has been synthesized and analyzed, i.e., YBa1.95Cs0.05Cu3O7−y. Its crystallographic structure is given. Two well-defined "critical regimes" are observed at 86 and 90 K, respectively, on electrical resistivity measurements. Magnetoresistivity measurements are also reported for small magnetic field. No anomalous hysteresis is found. Features in these transport properties are interpreted in terms of phase mixtures. The interest of such data is emphasized.
