Soft x-ray magnetic circular dichroism study of Ca_1-xSr_xRuO_3 across the ferromagnetic quantum phase transition
J. Okamoto, T. Okane, Y. Saitoh +10
Ca_1-xSr_xRuO_3, which is ferromagnetic for Sr concentration x > 0.3, has been studied by x-ray magnetic circular dichroism (XMCD) in Ru 3p and O 1s core-level x-ray absorption. XM…
Electronic structure of the strongly hybridized ferromagnet CeFe2
T. Konishi, K. Morikawa, K. Kobayashi +8
We report on results from high-energy spectroscopic measurements on CeFe2, a system of particular interest due to its anomalous ferromagnetism with an unusually low Curie temperatu…
Metal-insulator Crossover Behavior at the Surface of NiS_2
D. D. Sarma, S. R. Krishnakumar, E. Weschke +8
We have performed a detailed high-resolution electron spectroscopic investigation of NiS and related Se-substituted compounds NiSSe, which are known to be gapped in…
Indication of intrinsic room-temperature ferromagnetism in Ti1-xCoxO2-d thin film: An x-ray magnetic circular dichroism study
K. Mamiya, T. Koide, A. Fujimori +6
Soft x-ray magnetic circular dichroism (XMCD) measurements at the Co L2,3 edges of Co doped rutile TiO2 at room temperature have revealed clear multiplet features characteristic of…
High-energy spectroscopic study of the III-V nitride-based diluted magnetic semiconductor GaMnN
J. I. Hwang, Y. Ishida, M. Kobayashi +12
We have studied the electronic structure of the diluted magnetic semiconductor GaMnN ( = 0.0, 0.02 and 0.042) grown on Sn-doped -type GaN using photoemission an…
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,…
