Room Temperature Ferromagnetic Semiconductor Rutile Ti1-xCoxO2-δEpitaxial Thin Films Grown by Sputtering Method
Takashi Yamasaki, Tomoteru Fukumura, Masaki Nakano +2
Room temperature ferromagnetic semiconductor rutile Ti1-xCoxO2-δ(101) epitaxial thin films were grown on r-sapphire substrates by a dc sputtering method. Ferromagnetic magnetizatio…
Signature of Carrier-Induced Ferromagnetism in Ti_{1-x}Co_{x}O_{2-delta}: Exchange Interaction Between High-Spin Co 2+ and the Ti 3d Conduction Band
J. W. Quilty, A. Shibata, J. -Y. Son +5
X-ray photoemission spectroscopy measurements were performed on thin-film samples of rutile Ti_{1-x}Co_{x}O_{2-delta} to reveal the electronic structure. The Co 2p core level spect…
Carrier induced ferromagnetism in room temperature ferromagnetic semiconductor rutile TiO2 doped with Co
H. Toyosaki, T. Fukumura, Y. Yamada +5
A ferromagnetic semiconductor, rutile (Ti,Co)O2, exhibits anomalous Hall effect at room temperature. Strong dependence of the anomalous Hall effect, as well as the magneto-optic re…
Magneto-Optical Spectroscopy of Anatase TiO2 Doped with Co
T. Fukumura, Y. Yamada, K. Tamura +10
Magneto-optical spectroscopy of a transparent ferromagnetic semiconductor, anatase TiO2 doped with Co, is carried out at room temperature. A large magneto-optical response with fer…
