Abstract

A new iron-based superconductor, Lix(C6H16N2)yFe2-zSe2, with Tc = 38K has successfully been synthesized via the intercalation of lithium and hexamethylenediamine into FeSe. The superconducting transition has been confirmed not only by magnetic susceptibility measurements but also by electrical resistivity ones. The interlayer spacing, namely, the distance between neighboring Fe layers, d, is 16.225(5) Å, which is the largest among those of FeSe-based intercalation compounds. It has been found that the dependence of Tc on d in FeSe-based intercalation superconductors appears domic.
