Spin gaps in heavily overdoped BaFe2-xNixAs2

A direct correlation between spin excitations and superconductivity in iron-based superconductors is the evolution of low energy spin excitations in the over-doped region.In...铁基超导体（iron-based superconductors）中，自旋激发（spin excitations）与超导性（superconductivity）之间的直接关联，体现为过掺杂区（over-doped region）内低能自旋激发的演化规律。In...
