Contribution

It provides experimental resistivity data in high magnetic fields and critically evaluates the vortex-glass model's applicability to BSCCO-2212.

Findings

Data inconsistent with the vortex-glass scenario

Challenging of the vortex-glass interpretation by recent theories

Analysis of angular dependence of resistivity

Abstract

We present results for the in-plane resistivity as a function of temperature for clean single crystal samples of BSCCO-2212 in applied magnetic fields above 0.5 T. Several fixed angles between the magnetic field and the crystal c-axis were studied. The data were analysed in terms of the vortex-glass (VG) model, as suggested by previous experimental studies. Several features of the data were found to be inconsistent with the VG scenario. Recent theoretical studies have challenged the VG interpretation, and these are discussed in terms of our data.
