N2 - A polycrystalline FeTe1-xSx sample was synthesized using a solid-state reaction method. Magnetization data obtained in the zero-field cooling and field-cooling regimes revealed a superconductivity transition with the critical temperature Tc≈10K. 57Fe Mössbauer spectra were recorded in the temperature interval from 5.4 to 300 K in transmission geometry to reveal three components below 77 K: two magnetic and one paramagnetic. One of the magnetic components and the paramagnetic component belong to the FeTe1-xSx phase. Unusual behavior of hyperfine field for the smaller of the magnetic components was observed, signifying possible competition between antiferromagnetism and superconductivity.
