Description

A Bi2Sr2CaCu2O8 crystal selectively irradiated near the edges is studied using a Hall-sensor array. Vortices penetrating into the central Jc = 0 region are open-quotes focusedclose quotes in the center of the sample on increasing the applied field. In decreasing field, vortices leave the center and a large vortex accumulation is observed on the inner rim of the irradiated region. Spatially resolved magnetization measurements confirm the developed theoretical model
