Temperature dependence of the ultrasonic attenuation a and the sound velocity Vs have been measured in a Lal.85Sro.15CuO4 single crystal under the magnetic field. A jump and a kink in Vs have been observed at the superconducting transition temperature Tc in the C33 and the CI! mode, respectively. A

An increase of the sound velocity reflecting the elastic constant of the flux line lattice and its pinning are observed in the mixed states of a La1.ssSro.15Cu04 single crystal. Each anisotropic activation energy which is necessary to depin the flux line lattice is evaluated independently from measu

The anisotropy of the activation energy of the flux pinning in a LaL85Sr0.~sCuO 4 single crystal was investigated by ultrasonic measurements in various directions of wave vector k, polarization vector u and magnetic fields H. The large activation energy of U(0 K, 14 T) = 972 K and small field depend
