Growth of (NaxKy)FezSe2 crystals by chlorides flux at low temperatures
arXiv:1408.2181 · doi:10.1016/j.jcrysgro.2014.07.028
Abstract
(NaxKy)FezSe2 crystals are prepared by Na, Fe, and Se as starting materials in NaCl/KCl flux at low temperatures~720 °C. It is found that K is more preferred than Na to enter in between FeSe layers and forms the phase. Thus-obtained crystals contain more superconducting phase in volume fraction and exhibit new features in transport property. Our results provide a promising new synthetic route for preparing quality crystals of iron selenide superconductors.
