Abstract
Extensive measurements of a.c. susceptibility have been carried out on Bi2Sr2Ca1Cu2Ox single crystals with different matching fields B-Phi. The superconducting transition and dissipation peak become sharper in the field much higher than B-Phi. Flux pinning and interlayer coupling are believed to persist much above B-Phi. A line-like behaviour of vo rtices can exist up to a higher field than B-Phi and couples the layer . (C) 1998 Elsevier Science Ltd. All rights reserved.
