Spin susceptibility and effective mass of two-dimensional electrons in MgxZn1-xO/ZnO heterostructures
A. Tsukazaki, A. Ohtomo, M. Kawasaki +9
We report measurements of the spin susceptibility and the electron effective mass for two-dimensional electrons confined at the interfaces of MgxZn1-xO/ZnO single heterostructures…
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…
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…
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…
