✦ Synopsis

Ultrasonic measurements were carried out on a series samples of Ndz-xCexCuOt-y with x ranged from o to 0.2. The anomalous chanaes in both attenuation and velocity around 170 to 200 K were found for the superconducting samples (x=0.15) during cooling, whereas no anomalies can be found in this region for non-superconducting samples. The implications of this phenomenon is discussed.
