High-field magnetization of a two dimensional spin frustration system Ni(TeO)X (X = Br and Cl)
J. L. Her, Y. H. Matsuda, K. Suga +4
High-field magnetization, M(), on Ni(TeO)X (X = Br and Cl) were measured by using a pulse magnet. These compounds have a two dimensional crystal structur…
Observation of half-integer quantum Hall effect in single-layer graphene using pulse magnet
Satoru Masubuchi, Ken-ichi Suga, Masashi Ono +3
We report magnetotransport measurements on a single-layer graphene in pulsed magnetic fields up to = 53 T. With either electron- or hole-type charge carriers, the Hall resistan…
Intrinsic mechanism for high temperature ferromagnetism in GaMnN
Saki Sonoda, Isao Tanaka, Hidekazu Ikeno +9
Considerable efforts have been devoted recently to synthesize diluted magnetic semiconductors having ferromagnetic properties at room temperature because of their technological imp…
Properties of Ferromagnetic Ga1-xMnxN Films Grown by Ammonia-MBE
Saki Sonoda, Hidenobu Hori, Yoshiyuki Yamamoto +5
Using ammonia as nitrogen source for molecular beam epitaxy, the GaN-based diluted magnetic semiconductor Ga1-xMnxN is successfully grown with Mn concentration up to x~6.8% and wit…
High TC ferromagnetism in diluted magnetic semiconducting GaN:Mn films
H. Hori, S. Sonoda, T. Sasaki +4
Wurtzite GaN:Mn films on sapphire substrates were successfully grown by use of the molecular beam epitaxy (MBE) system. The film has an extremely high Curie temperature of around 9…
