Experimental Detection of Sign-Reversal Pairing in Iron-Based Superconductors

Abstract

We propose a modified Josephson corner-junction experiment which can test whether the order parameter in the iron pnictides changes sign between the electron and hole pockets of the Fermi surface.

2 pages, 2 figures; After this paper was completed, we found a similar idea had been proposed by arXiv: 0812.4416: Published version
