Abstract

In order to investigate the behaviour of vortices in high-T_c superconductors under low magnetic fields, we performed scanning SQUID microscopy (SSM) on the ab surfaces of Bi_2.1Sr_1.8Ca(Cu_0.98Co_0.02) ₂O_y (Bi2212) single crystals at different temperatures and under different magnetic fields up to 0.8 G. The observed magnetic images clearly demonstrated vortex assembly structures for Bi2212. Vortices trapped inside Bi2212 single crystals tended to be arranged in a one-dimensional manner.
