Using a double squid magnetometer, the angular variations of transverse (M X ) and longitudinal (M Z ) components of the magnetization of a La 1.85 Sr 0.15 CuO 4 single crystal has been investigated as a function of field at temperatures as close as possible to the critical temperature of this sampl
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
