抄録

The ferromagnetic Ni nanoparticles could be epitaxially dispersed in the (Mg,Ni)O matrix by the oxide reduction. For this purpose, the epitaxial (Mg0:5Ni0:5)O thin film was grown at room temperature by pulsed laser deposition and successively reduced at 700-C in hydrogen gas atmosphere. X-ray diffraction confirmed in-plane and out-of-plane epitaxial precipitation of Ni nanoparticles in the (Mg,Ni)O matrix by selective reduction of the Ni-O part in the epitaxial (Mg0:5Ni0:5)O thin film. Atomic-scale analyses indicated uniform dispersion of Ni nanoparticles (∼20 nm average size) in the (Mg,Ni)O matrix. Magnetic measurement confirmed ferromagnetic property of the Ni nanoparticle-containing (Mg,Ni)O thin films.
