A possible model to high TC ferromagnetism in Gallium Manganese Nitrides based on resonation properties of impurities in semiconductors
H. Hori, Y. Yamamoto, S. Sonoda
The high TC ferromagnetism in (Ga,Mn)N were observed and almost all results are approximately similar to the experimental results in (Ga,Mn)As except the value of TC. Though all st…
Direct evidence for ferromagnetic spin polarization in gold nanoparticles
Y. Yamamoto, T. Miura, T. Teranishi +7
We report the first direct observation of ferromagnetic spin polarization of Au nanoparticles with a mean diameter of 1.9 nm using X-ray magnetic circular dichroism (XMCD). Owing t…
Diameter dependence of ferromagnetic spin moment in Au nanocrystals
H. Hori, Y. Yamamoto, T. Iwamoto +3
Au nanoparticles exhibit ferromagnetic spin polarization and show diameter dependence in magnetization. The magnetic moment per Au atom in the particle attains its maximum value at…
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…
Molecular Beam Epitaxy of Wurtzite (Ga,Mn)N Films on Sapphire(0001) Showing the Ferromagnetic Behaviour at Room Temperature
S. Sonoda, S. Shimizu, T. Sasaki +2
Wurtzite (Ga,Mn)N films showing ferromagnetic behaviour at room temperature were successfully grown on sapphire(0001) substrates by molecular beam epitaxy using ammonia as nitrogen…
