Metal-insulator transitions
Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of orders of magnitude, and are widely observed in condensed-matter systems. This article...

We have studied the electronic structure of Mn impurities in GaAs by Mn 2p core-level photoemission spectroscopy. From cluster-model analysis assuming the neutral (Mn3+) or nega...

We present soft-x-ray-absorption spectra (XAS) of ${\mathrm{LaCoO}}_{3}$ taken at different temperatures (80--630 K). The shape of the multiplets in the Co 2p XAS spectra convey...
Soft-x-ray-absorption studies of the location of extra charges induced by substitution in controlled-valence materials
We present high-resolution 2p x-ray-absorption spectra from 3d transition metals M in three series of pseudobinary and pseudoternary oxides. We show how the detailed shape of th...
Valence-band photoemission and optical absorption in nickel compounds
Photoemission, optical-absorption, and isochromat spectra of NiO and ${\mathrm{NiCl}}_{2}$ are studied theoretically by the consideration of configuration interactions within th...
Multielectron satellites and spin polarization in photoemission from Ni compounds
Valence-band photoemission and its spin polarization of insulating Ni (${\mathrm{Ni}}^{2+}$:${d}^{8}$) compounds are studied by considering configuration interactions within the...
