Description
The authors investigated elastic anomalies of sintered YBa2Cu3O7-x (x=0.35) superconductor around the critical temperature (Tc = 60K). They observed the non-symmetric and large attentuation peak (2 dB/cm at 9.7 MHz) at Tc, which was due to the lattice softening caused by the strong correlation between carriers and local lattice distortion. The rapid decrease of ultrasonic attenuation just below Tc suggested a condensation mechanism. These supported the polaronic condensation in high-Tc superconductivity
