Investigation on a high-To superconductor, Lal.ssSro.15CuO4, was performed in the wide range of Q E space by means of neutron scattering and synchrotron radiation. The structure as well as the phonon dynamics showed a clear evolution at To. We found a spontaneous strain and phonon softening, which p

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
