Abstract

Acoustic properties of κ-(BEDT-TTF)₂Cu(NCS)₂, Y_1-XPr_XBa₂Cu₃O_y and CeRu₂ have been investigated. The organic superconductor κ-(BEDT-TTF)₂Cu(NCS)₂, shows a remarkable softening in the magnetic field. Elastic hardening has been observed in Y_1-XPr_XBa₂Cu₃O_y and CeRu₂. The elastic anomalies in the magnetic field have been considered based on the various couplings between the vortices and ultrasonic wave.
