Research Abstract |
Fermi surface plays an important role on superconductivity and magnetism in strongly correlated materials which draws attention as next-generation materials for electronic devices. In this study, we have developed the Compton scattering technique as a direct observation method of Fermi surfaces and then applied to novel superconductors. We measured cobaltates, Fe-As materials and cuprates, and succeeded in mapping out the Fermi surfaces and orbitals of carriers (holes or electrons) which play an important role in the occurrence of superconductivity.
