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

Single crystals of La 1:8 Sr 0:2 CuO 4รd grown by the traveling solvent floating zone method have been ground to spherical shape for studies of anisotropic supercondcucting properties by SQUID magnetometry. Here, we report on magnetization measurements parallel and perpendicular to the c-axis of one
Anisotropy of the upper critical field H 2 has been investigated in detail for single-crystal La 1 R6SrO 14Cu04 grown by the TSFZ method. c When magnetic fields are applied in the (110)t plane, large an1S0tropy of H , H ~/H H ~10, is observed and the angular dependence is well expressed by
