Valence changes associated with the metal-insulator transition in BiLaNiO
H. Wadati, M. Takizawa, T. T. Tran +9
Perovskite-type BiNiO is an insulating antiferromagnet in which a charge disproportionation occurs at the Bi site. La substitution for Bi suppresses the charge disproportionati…
Characterization of Magnetic Components in the Diluted Magnetic Semiconductor ZnCoO by X-ray Magnetic Circular Dichroism
M. Kobayashi, Y. Ishida, J. l. Hwang +12
We report on the results of x-ray absorption (XAS), x-ray magnetic circular dichroism (XMCD), and photoemission experiments on {\it n}-type ZnCoO () thin film,…
Polaronic behavior of undoped high-Tc cuprates
O. Rösch, O. Gunnarsson, X. J. Zhou +6
We present angle-resolved photoemission spectroscopy (ARPES) data on undoped La2CuO4, indicating polaronic coupling between bosons and charge carriers. Using a shell model, we calc…
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…
Temperature-dependent soft x-ray photoemission and absorption studies of charge disproportionation in LaSrFeO
H. Wadati, A. Chikamatsu, R. Hashimoto +7
We have measured the temperature dependence of the photoemission and x-ray absorption spectra of LaSrFeO (LSFO) epitaxial thin films with , where charge dis…
Photoemission study of poly(dA)-poly(dT) DNA : Experimental and theoretical approach to the electronic density of states
Hiroki Wadati, Kozo Okazaki, Yasuhiro Niimi +4
We present results of an ultraviolet photoemission spectroscopy study of artificially synthesized poly(dA)-poly(dT) DNA molecules on -type Si substrates. For comparison, we also…
