Description

This paper reports on the transition temperature of YBa2Cu3Oy ceramic samples studied as a function of oxygen content by DC electrical resistivity measurements. Two series of samples had been prepared by equilibrating pieces from the fully oxidized orthorhombic and fully reduced tetragonal phase at low (series I 420 degrees C) and high (series II 600 degrees C) temperatures. The Tc vs. oxygen content dependence was found to show a continuous change in series II and a 55 K plateau around y = 6.6-6.7 in series I. A current dependence was observed in series I in the range y = 6.5-6.6 where room temperature x-ray data may indicate the occurrence of more than one orthorhombic phases
