Title: Vortex Flow and Transverse Flux Screening at the Bose Glass Transition

Abstract

We study the vortex phase diagram in untwinned YBCO crystals with columnar defects. These randomly distributed defects are expected to induce a ''Bose glass'' phase of localized vortices exhibiting a vanishing resistance and Meissner effect for magnetic fields H{sub (perpendicular} {sub sign)} transverse to the columns. We directly observe the transverse Meissner effect using a Hall probe array. As predicted, the Meissner state breaks down at temperatures T{sub s} that decrease linearly as H{sub (perpendicular} {sub sign)} increases. However, T{sub s} lies far below the conventional melting temperature T{sub m} determined by a vanishing resistivity, suggesting a regime where vortices are effectively localized even when rotated off the columnar defects.
