Structure of spin excitations in heavily electron-doped Li0.8Fe0.2ODFeSe superconductors
Abstract
The microscopic mechanism underlying an enhanced superconductivity in electron-doped iron selenide superconductor remains unclear. Here, Pan et al. report the spin excitations of Li0.8Fe0.2ODFeSe, revealing analogous momentum structure and dispersion to hole-doped cuprates.
