AbstractMagnetic decoration has been used to investigate the role of surface pinning on the flux-line lattice (FLL) of high-quality Bi2Sr2CaCu2O8+ single crystals. We find that surface steps pin flux lines at the sample surface, and that strong pinning along large steps creates grain boundaries (GBs) in the FLL. Analysis of the competing energetics of pinning versus GB formation leads to a criteria for the formation of extended GBs, and also indicates that these GBs penetrate through the entire sample. Surface pinning, which should occur in all real samples, will thus significantly affect the bulk FLL structure in these materials. © 1994 The American Physical Society.
