In-situ photoemission study of Pr_{1-x}Ca_xMnO_3 epitaxial thin films with suppressed charge fluctuations
H. Wadati, A. Maniwa, A. Chikamatsu +7
We have performed an {\it in-situ} photoemission study of Pr_{1-x}Ca_xMnO_3 (PCMO) thin films grown on LaAlO_3 (001) substrates and observed the effect of epitaxial strain on the e…
Gradual Disappearance of the Fermi Surface near the Metal-Insulator Transition in LaSrMnO
A. Chikamatsu, H. Wadati, H. Kumigashira +6
We report the first observation of changes in the electronic structure of LaSrMnO (LSMO) across the filling-control metal-insulator (MI) transition by means of…
Effect of strong localization of doped holes in angle-resolved photoemission spectra of LaSrFeO
H. Wadati, A. Chikamatsu, M. Takizawa +9
We have performed an angle-resolved photoemission spectroscopy study of LaSrFeO using {\it in situ} prepared thin films and determined its band structure. The e…
Robust Ti4+ states in SrTiO3 layers of La0.6Sr0.4MnO3/SrTiO3/ La0.6Sr0.4MnO3 junctions
H. Kumigashira, A. Chikamatsu, R. Hashimoto +8
We have investigated the interfacial electronic structure of La0.6Sr0.4MnO3 (LSMO)/ SrTiO3 (STO)/ LSMO heterojunctions utilizing the elemental selectivity of photoemission spectros…
The band structure and Fermi surface of LaSrMnO thin films studied by in-situ angle-resolved photoemission spectroscopy
A. Chikamatsu, H. Wadati, H. Kumigashira +8
We have performed an in situ angle-resolved photoemission spectroscopy (ARPES) on single-crystal surfaces of LaSrMnO (LSMO) thin films grown on SrTiO (0…
Manifestation of Correlation Effects in the photoemission spectra of CaSrRuO
M. Takizawa, D. Toyota, H. Wadati +8
We have measured soft x-ray photoemission and O 1{\it s} x-ray absorption spectra of CaSrRuO thin films prepared {\it in situ}. The coherent and incoherent parts ha…
