Theory of BiSrCaCuO Cross-Whisker Josephson Junctions
arXiv:cond-mat/0211423 · doi:10.1103/PhysRevB.67.174509
Abstract
Takano {\it et al.} [Phys. Rev. B {\bf 65}, 140513 (2002) and unpublished] made Josephson junctions from single crystal whiskers of BiSrCaCuO crossed an angle about the axis. From the mesa structures that formed at the cross-whisker interface, they inferred a critical current density . Like the single crystal results of Li {\it et al.} [Phys. Rev. Lett. {\bf 83}, 4160 (1999)], we show that the whisker data are unlikely to result from a predominantly d-wave order parameter. However, unlike the single crystals, these results, if correct, require the whisker c-axis transport to be coherent.
