โฆ Synopsis
Magneto-optical imaging and direction-dependent resistivity measurements are cross-correlated to provide evidence that the extended line defects in Bi 2 Sr 2 CaCu 2 O 8 single crystals are needle-like Bi 2 Sr 2 Ca 2 Cu 3 O 10 intergrowths that form along the crystal growth direction.

Magnetic hysteresis curves as well as reversible magnetization in the superconducting state of single crystalline Bi2Sr2CaCu208+6 have been studied. Large hysteresis in magnetization at 4.2 K, which is a manifestation of strong pinning effects, rapidly diminishes around 25 K, where an anomalous peak
