摘要：

Normal-state electrical resistance measurements were made on single crystal YBa2Cu3O7-δ over the temperature range 200-800°C in oxygen and argon atmospheres, and the twin structure was observed simultaneously by hot-stage optical microscopy. The resistance of the crystal maintained a linear metallic-type behavior to higher temperatures (500°C) than reported for bulk ceramic specimens. Anomalous resistance behavior was observed in the vicinity of the orthorhombic-to-tetragonal phase transformation under certain probe configurations and measuring conditions. Correlations between observed in situ twinning and resistance characteristics are discussed. © 1990.
