Hole-doping-induced changes in the electronic structure of LaSrFeO : soft x-ray photoemission and absorption study of epitaxial thin films
H. Wadati, D. Kobayashi, H. Kumigashira +9
We have studied the electronic structure of epitaxially grown thin films of LaSrFeO by {\it in-situ} photoemission spectroscopy (PES) and x-ray absorption spectrosc…
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…
