We have measured the temperature dependence of the thermal conductivity ~b in direction parallel to the copper-oxygen planes for a single crystal of LaLssSr0.1sCuO4-~ in the temperature range from I.gK to 50K. tcab shows the enhancement at the superconducting transition temperature T~. Below 15K, tz
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
