Quenching Dependence on Superconductivity in the Synthesizing Process of Single Crystals of Rb $_{x}$ Fe $_{2 - y}$ Se $_{2}$

Abstract

Superconducting single crystals of Rb-intercalated FeSe compounds Rb $_{x}$ Fe $_{2 - y}$ Se $_{2}$ were prepared by using a starting material of Rb $_{2}$ Se as a Rb source. The superconducting properties and the surface microstructures were systematically controlled by varying the cooling rate in the quenching process. The higher cooling rate in the sample provided a higher superconducting transition temperature with highly connected superconducting mesh-like surface structure. Extremely slow-cooling process led to the complete isolation between the superconducting domains.
