TL;DR: The synthesis of large single crystals of a new FeSe layer superconductor Cs( 0.8)(FeSe(0.98))(2) is reported on, which shows a slightly lower superconducting transition temperature and the T(c) dependence on the anion height was found to be analogous to those reported for As-containing Fe superconductors and Fe(Se(1 - x)Ch(x)), where Ch = Te, S.

TL;DR: In this paper, the synthesis of large single crystals of a new FeSe-layer superconductor Cs0.8(FeSe0.98)2 has been reported.

TL;DR: Data from muon-spin rotation and relaxation, electrical resistivity, magnetization and differential scanning calorimetry measurements performed on a high-quality single crystal indicate a microscopic coexistence between the superconducting phase and a strong magnetic phase.

TL;DR: The findings indicate a new synthesis route leading to possibly even higher critical temperatures for materials in this class: by intercalation of organic compounds between Fe-Se layers.

TL;DR: In this article, a solution for the atomic structure is found in the space group $I4/m$ with an ordered pattern of iron vacancies corresponding to the iron deficiency $x = 0.29$ and Cs stoichiometry $y=0.83$.
