Disorder-dependent superconducting phase-diagram at high magnetic fields in Fe${}_{1+y}$Se${}_x$Te${}_{1-x}$ ($x\sim 0.4$)

T. Gebre, G. Li, J. B. Whalen +7

We compare the superconducting phase-diagram under high magnetic fields (up to $H=45$ T) of Fe${}_{1+y}$Se${}_{0.4}$Te${}_{0.6}$ single crystals originally grown by the Bridgman-Stockb…
