Single crystals of La_1.8Sr_0.2CuO_4-\delta grown by the travelling 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 on two of these crystals. At low enough temperatures and fields the spheres are perfectly shielding (susceptibility -1.5 [SI]) and thus magnetically isotropic. The field dependence of the critical…

Flux flow of La-Sr-Cu-O single crystals

We measured voltages across micro-bridges fabricated along the c-axis of La/sub 2-x/Sr/sub x/CuO/sub 4/ single crystals under an external magnetic field. A sharp voltage peak appears when the
