Frequency-dependent ultrasonic attenuation of YBa2Cu3O7
- 1. NASA Langley Research Center, Hampton, Virginia 23665
Description
At temperatures near T/sub c/ experimental measurements of temperature-dependent ultrasonic attenuation at three frequencies exhibit maxima, and velocity measurements display softening of the lattice. These attenuation maxima result from a relaxation process which occurs around the superconducting transition, and the softening of velocity arount T/sub c/ may evidence a structural instability in YBa2Cu3O7 at these temperatures
