It has only been a few years since the discovery of superconductivity in the iron-arsenic compound family. Yet, a lot of work, both theoretical and experimental, has been done on this material. So it is inevitable that, at some point, a review of what we know so far will appear. This is one such review.
Abstract: In this review, the authors present a summary of experimental reports on newly discovered iron-based superconductors as they were known at the end of 2008. At the same time, this paper is intended to be useful for experimenters to know the current status of these superconductors. The authors introduce experimental results that reveal basic physical properties in the normal and superconducting states. The similarities and differences between iron-pnictide superconductors and other unconventional superconductors are also discussed.
Certainly helpful to have a catalog of something like this periodically.
