Abstract

In alkali metal intercalated iron selenide crystals only about 10–15% of the material volume displays superconductivity the rest is antiferromagnetic and not superconducting below Tc ~ 30 K. The superconducting phase is homogeneously distributed within the volume of the crystal creating three-dimensional networks of micrometer-size fibers. In the paper ideas concerning the origin of the observed phase separation are briefly presented.
