Friedel-like Oscillations from Interstitial Iron in Superconducting Fe1+yTe0.62Se0.38

V. Thampy, J. Kang, J. A. Rodriguez-Rivera +14

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 a…
