Investigation of neamtic phase in LaFeAsO

ORAL

Abstract

The nematic phase is belived to play a key role in iron based superconductor (IBSC), but it is not fully understood. LaFeAsO, known to have nematic phase but its electronic structure is not well understood, is a good system to get new clues about the nematic phase. To investigate the electronic structure of LaFeAsO nematic phase, we performed angle resolved phtoemisson spectroscopy (APRES) experiment. We report temperature dependent band splitting behavior between dxz and dyz hole band near Γ and M point
