Low-energy spin excitations in Ni over-doped NaFe0.7Ni0.3As
The discovery of iron-based superconductors gives a new horizon to study unconventional superconductivity. Typically iron-based superconductors can be created by doping (i.e.... -
High Energy Spin Excitations in Electron Overdoped NaFe0.7Ni0.3As
The interplay between magnetism and superconductivity in iron-based high-temperature superconductors are of great interest in condensed matter physics research. These two...
