Temperature-Dependence of Magnetically-Active Charge Excitations in Magnetite across the Verwey Transition
M. Taguchi, A. Chainani, S. Ueda +16
We have studied the electronic structure of bulk single crystals and epitaxial films of magnetite FeO. Fe core-level spectra show clear differences between hard x-ray…
Electronic excitations of magnetic impurity state in diluted magnetic semiconductor (Ga,Mn)As
M. Kobayashi, H. Niwa, Y. Takeda +9
The electronic structure of doped Mn in (Ga,Mn)As is studied by resonant inelastic X-ray scattering (RIXS). From configuration-interaction cluster-model calculations, the line shap…
Electronic structure of an antiferromagnetic metal: CaCrO3
P. A. Bhobe, A. Chainani, M. Taguchi +11
We report on the electronic structure of the perovskite oxide CaCrO3 using valence-band, core-level, and Cr 2p - 3d resonant photoemission spectroscopy (PES). Despite its antiferro…
Nanoscale Dichotomy of Ti 3d Carriers Mediating the Ferromagnetism in Co:TiO2 Anatase Thin Films
T. Ohtsuki, A. Chainani, R. Eguchi +11
We study the surface and bulk electronic structure of the room-temperature ferromagnet Co:TiO2 anatase films using soft and hard x-ray photoemission spectroscopy with probe sensiti…
Evidence for a correlated insulator to antiferromagnetic metal transition in CrN
P. A. Bhobe, A. Chainani, M. Taguchi +15
We investigate the electronic structure of Chromium Nitride (CrN) across the first-order magneto-structural transition at T_N ~ 286 K. Resonant photoemission spectroscopy shows a g…
Out-of-plane nesting driven spin spiral in ultrathin Fe/Cu(001) films
J. Miyawaki, A. Chainani, Y. Takata +5
Epitaxial ultrathin Fe films on fcc Cu(001) exhibit a spin spiral (SS), in contrast to the ferromagnetism of bulk bcc Fe. We study the in-plane and out-of-plane Fermi surfaces (FSs…
