Author(s): F. Ye, S. Chi, Wei Bao, X. F. Wang, J. J. Ying, X. H. Chen, H. D. Wang, C. H. Dong, and Minghu Fang Single-crystal neutron diffraction studies on superconductors A 2 Fe 4 Se 5 , where A=Rb , Cs, (Tl, Rb), and (Tl, K) ( T c ∼30 K ), uncover the same Fe vacancy ordered crystal structure and the same block antiferromagnetic order as in K 2 Fe 4 Se 5 . The Fe order-disorder transition occurs at T S =500–578 K , and the... [Phys. Rev. Lett. 107, 137003] Published Mon Sep 19, 2011
