“…Therefore, a mixture of CsCl and KCl (CsCl/KCl) is a promising flux as it exhibits little reactivity to quartz tubes at high temperatures. [11][12][13] In this paper, we focus on the compound NdO 1-x F x BiS 2 (x=0.1-0.7), which was found to have a maximum T c of 5.6 K at x=0.3. 5) We report the successful growth of F-substituted NdOBiS 2 single crystals using CsCl/KCl as the flux with a eutectic temperature of approximately 616 °C in a quartz tube sealed in vacuum.…”

F-substituted NdOBiS 2 superconducting single crystals were grown using CsCl/KCl flux. This is the first example of the single-crystal growth of a BiS 2 -based superconductor. The obtained single crystals had a plate-like shape with a size of 1-2 mm and a well-developed ab-plane. The crystal structure of the grown crystals was determined by single-crystal X-ray diffraction analysis to be the tetragonal space group P4/nmm (#129) with a = 3.996(3) Å and c = 13.464(6) Å. The chemical formula of the grown crystals was approximately Nd 0.98±0.06 O 0.7±0.

“…However, R(O,F)BiS 2 cannot be synthesized using LiCl and NaCl fluxes in a vacuum quartz tube at high temperatures because these alkali chlorides would corrode the quartz tube. A mixture of CsCl and KCl (CsCl/KCl) is a promising flux, as it exhibits little reactivity to quartz tubes at high temperatures [19][20][21].…”

R(O,F)BiS 2 (R: La, Ce, Pr, Nd) superconducting single crystals with different F concentrations are grown using a CsCl/KCl flux. The obtained 1-2 mm-sized single crystals have a plate-like shape and are cleavable along the ab-plane. The crystal structure is tetragonal of space group P4/nmm (#129). The as-grown single crystals exhibit superconductivity at around 3-5 K. The superconducting transition temperature increases with decreasing the ionic radius of the R element. The superconducting anisotropies of the R(O,F)BiS 2 single crystals are estimated to be 30-60 according to the effective mass model, whereas the anisotropies for Ce(O,F)BiS 2 single crystals are 13-21. The c-axis transport measurements of a single crystal of Pr(O,F)BiS 2 under a magnetic field parallel to the ab-plane reveal a "lock-in" state attributed to the Josephson vortex flow. Furthermore, the Ce(O,F)BiS 2 single crystals exhibit a magnetic order at the temperature range of 5-7 K that apparently coexist with superconductivity below approximately 3 K.

“…The LaO 1−x F x BiSe 2 single crystals were grown by flux method using a mixture of CsCl and KCl as the flux (the molar ratio of CsCl : KCl is 5 : 3) [18][19][20][21] . The starting materials of high-purity Bi 2 O 3 , BiF 3 , Bismuth, Lanthanum and Selenium were weighed with nominal concentrations of LaO 1−x F x BiSe 2 and thoroughly ground in an agate mortar.…”

F-doped LaOBiSe2 superconducting single crystals with typical size of 2×4×0.2 mm 3 are successfully grown by flux method and the superconducting properties are studied. Both the superconducting transition temperature and the shielding volume fraction are effectively improved with fluorine doping. The LaO0.48F0.52BiSe1.93 sample exhibits zero-resistivity at 3.7 K, which is higher than that of the LaO0.5F0.5BiSe2 polycrystalline sample (2.4K). Bulk superconductivity is confirmed by a clear specific-heat jump at the associated temperature. The samples exhibit strong anisotropy and the anisotropy parameter is about 30, as estimated by the upper critical field and effective mass model
