Tuning the superconducting and magnetic properties in Fe_ySe_0.25Te_0.75 by varying the Fe-content

M. Bendele, P. Babkevich, S. Katrych +7

The superconducting and magnetic properties of Fe${}_y$Se${}_{0.25}$Te${}_{0.75}$ single crystals ($0.9\le y\le 1.1$) were studied by means of x-ray diffraction, SQUID magnetometry,…
