High Energy Spin Excitations in Electron Overdoped NaFe0.7Ni0.3As

Abstract: The interplay between magnetism and superconductivity in iron-based high-temperature superconductors are of great interest in condensed matter physics research. These two properties can dramatically evolve with electron or hole doping in iron-based materials. To understand the interplay between magnetism and superconductivity and their co-evolution with doping across the phase diagram, magnetic excitation spectra obtained via neutron scattering are critical. Here we propose an inelastic neutron scattering experiment on high energy (mainly, also with low energy measurement) spin wave excitation in highly electron-doped NaFe0.7Ni0.3As to contribute to the magnetic excitation spectra of the NaFeAs family of superconductors, thus completing the phase diagram of it. We submitted the same proposal in 2016 and were granted 7 days beamtime, but the experiment canceled due to MAPS upgrade.
