Electronic Structure and Electron Correlation in LaFeAsO1-xFx and LaFePO1-xFx

Malaeb, Walid; Yoshida, Teppei; Kataoka, Takashi; Fujimori, Atsushi; Kubota, Masato; Ono, Kanta; Usui, Hidetomo (2008)

Photoemission spectroscopy is used to investigate the electronic structure of the newly discovered iron-based superconductors LaFeAsO 1- x F x and LaFePO 1- x F x . Line shapes of the Fe 2 p core-level spectra suggest an ...
Photoemission study of the electronic structure of LaFeAsO 1-xFx and LaFePO1-xFx

Malaeb, Walid; Yoshida, Teppei; Kataoka, Takashi; Fujimori, Atsushi; Kubota, Masato; Ono, Kanta; Usui, Hidetomo; Kuroki, Kazuhiko; Arita, Ryotaro; Aoki, Hideo (2008)

We have performed a photoemission spectroscopy study of the newly discovered iron-based superconductors LaFeAsO1-xFx and LaFePO1-xFx. The valence-band spectra show a narrow Fe 3d-derived band near EF indicating the itinerant ...
Three-Dimensional Electronic Structure of Superconducting Iron Pnictides Observed by Angle-Resolved Photoemission Spectroscopy

Malaeb, Walid; Yoshida, Teppei; Fujimori, Atsushi; Kubota, Masato; Ono, Kanta; Kihou, Kunihiro; Shirage, Parasharam M.; Kito, Hijiri (2009-11-25)

We have performed an angle-resolved photoemission spectroscopy (ARPES) study of the undoped and electron-doped iron pnictides BaFe 2- x Co x As 2 (Ba122) ( x = 0, 0.14) and studied the Fermi surfaces (FSs) and band dispersions ...
