Fe-based Superconductors: Unity or Diversity?

This is a short review article on the Fe-based superconductor in conjunction with a paper published in Nature Materials. However, it provides a nice summary of the Fe-based superconductors, especially on the important question of whether the Fe-based superconductor shares a similar behavior with the cuprate superconductors, or if they are of an entirely new physics. Based on the paper of J. Zhao et al. (Nature Mater. 7, 953 (2008)) which is being reviewed here, the conclusion is that the Fe-based family is similar to the cuprates.

Of course, at this stage of the game, this is still controversial, and it will take quite a bit more work to have a consensus. With the cuprate superconductor still yielding many surprises and disagreement, this could take a while.
