Abstract: The superconducting and magnetic properties of Fe$ {y}$Se$ {0.25}$Te$ {0.75}$single crystals $0.9\leq y \leq1.1$ were studied by means of x-raydiffraction, SQUID magnetometry, muon spin rotation, and elastic neutrondiffraction. The samples with $y<1$ exhibit coexistence of bulksuperconductivity and incommensurate magnetism. The magnetic order remainsincommensurate for $y\geq 1$, but with increasing Fe content superconductivityis suppressed and the magnetic correlation length increases. The results showthat the superconducting and the magnetic properties of theFe$ {y}$Se$ {1-x}$Te$ {x}$ can be tuned not only by varying the Se-Te ratio butalso by changing the Fe content.
