Abstract: We report synthesis of high quality Fe1+yTe1-xSxz single crystals and acomprehensive study of structural, magnetic and transport properties. There ishigh sensitivity to material stoichiometry which includes vacancies on theTeS site. Our results reveal competition and coexistence of magnetic orderand percolative superconductivity for x >= 0.03, while zero resistivity isacheived for x >= 0.1.
