Title Thickness effects on the pinning by columnar defects Type Journal Article
Year 2000 Publication PHYSICA C Abbreviated Journal
Volume 341 Issue Pages 1217-1218
Keywords
Abstract We compare the angular dependence of the pinning of equivalent columnar defects in GdBa2Cu2O7 thin films and a thicker YBa2Cu3O7 single crystal. The tracks' related enhancement of the critical currents is much smaller for the case of the thin films. We interpret this thickness dependence as resulting from a competition between the pinning of the correlated structures, related to total sample thickness, and surface boundary conditions, which force the vortices to depin from the columnar defects near the sample surface.
