Ferromagnetic interlayer coupling in FeSe1−xSx superconductors revealed by inelastic neutron scattering
FeSe1-xSx superconductors are commonly considered layered van der Waals materials with negligible interlayer coupling. Here, using inelastic neutron scattering to study spin excitations in single-crystal samples, we reveal that the magnetic coupling between adjacent Fe layers is ferromagnetic in nat...
