抄録

This paper reports on an ultrasonic study at 85 kHz and 485 kHz of melt-textured Y123 (YBa2Cu3O7-δ) where a possible structural change has been identified in the 220 K region. Work on oxygenated and partially deoxygenated samples has shown that the change is associated with oxygen in the samples and that the activation energy for the process is 110 meV. The conclusions are based on a qualitative and quantitative description of ultrasonic attenuation and ultrasonic velocity changes in the material as a result of slow thermal cycling and quenching experiments.
