We have synthesized single crystals of FeTe1-xSx and investigated the structural and physical properties. The actual S concentration was found to be significantly smaller than the starting nominal value. The solubility limit of S for the Te site for the crystals grown using a self-flux method was estimated to be around 12%. Although a suppression of antiferromagnetic transition was observed by S substitution, bulk superconductivity was not observed. A phase diagram of as-grown FeTe 1-xSx single crystal was established on the basis of the structural and physical properties. © 2010 IEEE.
