We report an investigation into the superconducting and magnetic properties of Fe₁₊ySeₓTe₁₋ₓ single crystals by magnetic susceptibility, muon spin rotation, and neutron diffraction. We find three regimes of behavior in the phase diagram for 0≤ x≤ 0.5: (i) commensurate magnetic order for x< 0.1, (ii) bulk superconductivity for x 0.1, and (iii) a range 0.25≤ x≤ 0.45 in which superconductivity coexists with static incommensurate magnetic order. The results are qualitatively consistent with a two-band mean-field model in which itinerant magnetism and extended s-wave superconductivity are competing order parameters.
