Synthesis, single-crystal growth, and superconducting properties of Fe-Se system

Single crystals FeSe x were grown by the vapor-transport reaction method using a polycrystalline material, a sealed quartz tube, and iodine I 2 . The single crystals grown are 0.1–0.5 mm in size and are characterized by hexagonal prismatic, tetragonal prismatic, platelike square, and hexagonal facet...

Zusammenfassung:Single crystals FeSe x were grown by the vapor-transport reaction method using a polycrystalline material, a sealed quartz tube, and iodine I 2 . The single crystals grown are 0.1–0.5 mm in size and are characterized by hexagonal prismatic, tetragonal prismatic, platelike square, and hexagonal faceting. Measurements of the electron-transport and magnetic properties of the FeSe x single crystals indicate the existence of a superconducting transition at 24 K.
