A RIXS study on Spin and Charge Excitations in Electron-Doped Cuprates, NCCO

The phase diagram of the high-Tc cuprates is known to exhibit intriguing asymmetric doping evolution between the hole and electron-doping. ARPES and inelastic neutron scattering experiments have been extensively applied to study cuprates on both sides of the phase diagram, revealing a distinct Fermi surface evolution between the hole- and electron-doped cuprates, and the properties of low energy spin excitations. In this presentation, I will report high energy spin excitations and charge excitations of electron-deoped cuprates, Nd2-xCexCuO4, measured via resonant inelastic x-ray scattering (RIXS) at the Cu L-edge. The doping evolution of these excitations and their differences with those of the hole-doped cuprates will be discussed.
