TL;DR
This study investigates the vortex liquid phase in irradiated BSCCO(2212) crystals by measuring c-axis resistivity under magnetic fields, revealing how vortex line segments are confined by defects and depend on magnetic field parameters.
Contribution
The paper provides new insights into the vortex line confinement and phase correlation lengths in irradiated BSCCO crystals, highlighting the effects of columnar defects on vortex structure.
Findings
Maximum vortex line length is about 15 interlayer distances.
Vortex line confinement depends on the filling factor f.
Resistivity measurements reveal the vortex liquid phase behavior.
Abstract
The c-axis resistivity in irradiated and in pristine BSCCO(2212) crystals is measured as a function of the in-plane magnetic field component at fixed out-of-plane component B_\perp in the vortex liquid phase at T=67 K. From this data we extract the dependence of the phase difference correlation length inside layers on B_\perp and estimate the average length of pieces of vortex lines confined inside columnar defects as a function of the filling factor f=B_\perp / B_\phi. The maximum length, about 15 interlayer distances, is reached near f=0.35.
