Description:
Author(s): K. M. Taddei, J. M. Allred, D. E. Bugaris, S. Lapidus, M. J. Krogstad, R. Stadel, H. Claus, D. Y. Chung, M. G. Kanatzidis, S. Rosenkranz, R. Osborn, and O. Chmaissem The authors present a careful phase diagram determination of the hole-doped Sr 1 − x Na x Fe 2 As 2 iron-based superconductors, with special attention paid to the region around x =0.36, where they recently found the existence of a magnetic C 4 phase. This phase has already proven instrumental in settling longstanding questions in these materials. In contrast to the two previous hole-doped Ba-based materials exhibiting this phase, here they find the C 4 phase to be more robust, existing over a larger range of compositions. This should prove useful for future studies. [Phys. Rev. B 93, 134510] Published Wed Apr 20, 2016
