Bulk and Surface Magnetization of Co atoms in Rutile Ti_[1-x]Co_xO_[2-delta] Thin Films Revealed by X-Ray Magnetic Circular Dichroism
V. R. Singh, Y. Sakamoto, T. Kataoka +10
We have studied magnetism in Ti_[1-x]Co_xO_[2-δ] thin films with various x and δby soft x-ray magnetic circular dichroism (XMCD) measurements at the Co L_[2,3] absorption edges. Th…
Role of charge carriers for ferromagnetism in cobalt-doped rutile TiO2
T Fukumura, H Toyosaki, K Ueno +2
Electric and magnetic properties of a high temperature ferromagnetic oxide semiconductor, cobalt-doped rutile TiO2, are summarized. The cobalt-doped rutile TiO2 epitaxial thin film…
X-ray Anomalous Scattering of Diluted Magnetic Oxide Semiconductors: Possible Evidence of Lattice Deformation for High Temperature Ferromagnetism
Takeshi Matsumura, Daisuke Okuyama, Shinya Niioka +7
We have examined whether the Co ions crystallographically substitute on the Ti sites in rutile and anatase Ti_{1-x}_{x}_{2-delta}$ thin films that exhibit room-temperature f…
A scaling relation of anomalous Hall effect in ferromagnetic semiconductors and metals
Tomoteru Fukumura, Hidemi Toyosaki, Kazunori Ueno +3
A scaling relation of the anomalous Hall effect recently found in a ferromagnetic semiconductor (Ti,Co)O_2_ is compared with those of various ferromagnetic semiconductors and metal…
Anomalous Hall effect in anatase Ti1-xCoxO2 at low temperature regime
Kazunori Ueno, Tomoteru Fukumura, Hidemi Toyosaki +2
Anomalous Hall effect (AHE) of a ferromagnetic semiconductor anatase \cotio thin film is studied from 10K to 300K. Magnetic field dependence of anomalous Hall resistance is coincid…
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…
