Single crystals of La1.8Sr0.2CuO4-δgrown by the traveling solvent floating zone method have been ground to spherical shape for studies of anisotropic superconducting properties by SQUID magnetometry. At low enough temperatures and fields, the spheres are perfectly shielding (susceptibility -1.5 [SI]...
