Abstract
The electrical resistivity, R, and its temperature derivative, dR/dT, have been measured for Y1Ba2Cu3O6+x as a function of temperature from 400°C up to 750°C. Both R and dR/dT reveal anomalous increments between about 450°C and 580°C. The increments in resistivity (excess resistivity), Δ R, and dR/dT have peaks at around 550±20°C. From the thermogravimetric measurements for the Y1Ba2Cu3O6+x samples, an anomaly was found to occur near the structural phase transition temperature. A possible origin of the anomaly is also discussed.Keywords
