Abstract
We have examined the sensitivity to low magnetic fields of c-axis transport in BSCCO (2212) bulk single crystals. A uniform field is applied along the ab planes of a mesa structure which was formed by etching. Four terminal volt-ampere curves in liquid nitrogen show a field dependent critical current and flux flow region followed by a multiple branch region, suggestive of stacks of hysteretic junctions.<>
