Overdoped cuprate superconductors are strange metals above their superconducting transition temperature. Here, the authors study La2-xSrxCuO4 by inelastic neutron scattering and numerical calculations, establishing that low-energy spin excitations and spatial disorder are central to the strange metal behaviour.
