Investigation of the spin-glass regime between the antiferromagnetic and superconducting phases in Fe${}_{1+y}$Se${}_x$Te${}_{1-x}$

N. Katayama, S. Ji, D. Louca +12

Using bulk magnetization along with elastic and inelastic neutron scattering techniques, we have investigated the phase diagram of Fe${}_{1+y}$Se${}_x$Te${}_{1-x}$ and the nature of ma…
