The dc susceptibility of Bi2Sr2CaCu2Ox single crystals has been measur
ed in very low magnetic fields, applied parallel and perpendicular to
c-axis. The Meissner and shielding effects have been observed for both
orientations. It has been found that low-field magnetic properties ar
e highly anisotropic. The incomplete shielding and Meissner effects ar
e discussed in terms of existing theoretical models.
