R(O,F)BiS₂ (R= La, Ce, Pr, Nd) are one of the BiS₂-based superconductor, which were reported the single crystals growth. And its intrinsic characteristics have been revealed. However, Sm(O,F)BiS₂ single crystals have never been grown and evaluated. Ionic radius of Sm is smaller than that of Nd. In this presentation, we have successfully grown Sm(O,F)BiS₂ single crystals using KI-KCl flux, and the evaluation of superconducting properties were performed.
