Abstract

We have measured ultrasonic absorption in sinter-forged high T_c YBa₂Cu₃O_{7 - δ}. Owing to the anisotropic properties of the sinter-forged samples, longitudinal ultrasonic attenuation measurements showed very strong anisotropy when waves were propagated parallel and perpendicular to the forging axis. Sound absorption was found to increase with decreasing temperature for shear waves travelling parallel to the forging axis.
