High-pressure growth of fluorine-free SmFeAsO${}_{1-x}$ superconducting single crystals

Hyun-Sook Lee, Jae-Hyun Park, Jae-Yeap Lee +6

Superconducting single crystals of SmFeAsO${}_{1-x}$ without fluorine doping were grown at a pressure of 3.3 GPa and a temperature of 1350-1450 ${}^{\circ }$C by using the self-flux metho…
