Abstract

Single crystals of LaO_0.5F_0.5Bi(S_0.8Se_0.2)₂ were grown by a CsCl-flux method. Electrical resistivity ρ(T) measurements were performed to reveal its superconducting properties. The ρ(T) of the single crystal shows semiconducting-like behavior and superconducting transition at 3.4 K. The value is slightly higher than that of the polycrystalline sample with substitution amounts of x = 0.2 (T_c ∼ 2.5 K). From ρ(T) measurements in several magnetic fields, μ₀H_c2^//ab(0) and μ₀H_c2^//c(0) are estimated to be 17.2 T and 0.59 T, respectively. The superconducting anisotropic parameter γ is determined to be 29.2.
