We combine soft X-ray, hard X-ray, and neutron inelastic scattering measurements to study both spin and charge excitations in electron-doped copper oxide superconductors. Thanks to the recent development of beam sources and related experimental techniques, accessible energy range of the these inelastic scattering measurements overlaps each other and it enables us to investigate spin and charge dynamics in the important but unexplored energy-momentum space of the cuprate superconductors. Our study demonstrates that complementary use of X-ray and neutron has become effective in inelastic scattering for studying electron dynamics of materials.
