Abstract

Using polarized and unpolarized neutron scattering, we show that interstitial Fe in superconducting Fe _1+y Te _1-x Se _x induces a magnetic Friedel-like oscillation that diffracts at Q=(120) and involves >50 neighboring Fe sites. The interstitial >2μ_B moment is surrounded by compensating ferromagnetic four-spin clusters that may seed double stripe ordering in Fe_1+y Te. A semimetallic five-band model with (½ ½) Fermi surface nesting and fourfold symmetric superexchange between interstitial Fe and two in-plane nearest neighbors largely accounts for the observed diffraction.
