Abstract

New superconductors, Lix(CnH2n+3N)yFe1-zSe (n = 6, 8, 18), have been synthesized via the co-intercalation of linear monoamines together with Li into FeSe. The distance between neighboring Fe layers expands up to 55.7 Å for n = 18, which is much larger than the previous record of 19Å in the FeSe-based intercalation superconductors. Tc remains saturated at ∼42 K.
