Suppression of the antiferromagnetic order when approaching the superconducting state in a phase-separated crystal of K${}_x$Fe${}_{2-y}$Se${}_2$

Shichao Li, Yuan Gan, Jinghui Wang +15

We have combined elastic and inelastic neutron scattering techniques, magnetic susceptibility and resistivity measurements to study single-crystal samples of K${}_x$Fe${}_{2-y}$Se${}_2$,…
