Orbital selective spin excitations and their impact on superconductivity of LiFe1-xCoxAs

Yu Li, Zhiping Yin, Xiancheng Wang +11

We use neutron scattering to study spin excitations in single crystals of LiFe${}_{0.88}$Co${}_{0.12}$As, which is located near the boundary of the superconducting phase of LiFe$_{1-x}…
