초록
We have investigated the behavior induced by Ga substitution in B-1212 system and observed an anomalous superconductor-like resistivity drop with an onset near 260 K and an offset at 248 K in the nominal (B0.65Ga0.35)(Ba1.25Sr0.75)(Er0.5Ca0.5)Cu2Oz compound. However, this property degraded with repeated cycling. Systematic studies of the superconducting properties of the (B1-xGax)(Ba1.25Sr0.75)(Er0.5Ca0.5)Cu2Oz compounds are reported and discussed in the context of the anomalous resistivity transition.
