Research Abstract

Fermi surface instability associated with SDW-type anti-ferromagnetic order draws much attention because the anti-erromagnetic phase and superconducting phase exist closely each other. In this study we have performed joint studies of high-resolution Compton scattering experiment and reconstruction method, and have revealed experimentally the relation between anti-ferromagnetic order and correlated itinerant electron system. We measured iron-based superconductors and cuprate superconductors. In the cuprates we found that the conducting doped holes in the under-doped region are influenced by the fluctuating anti-ferromagnetic order.
