＜正＞ Recently, the magnetic properties of magnetic nanoparticles have become a hot topic in magnetic materials. Single magnetic cluster with a few hundred or thousand atoms and the clusters embedded in nonmagnetic matrixes have been studied. The cluster contains both core and surface spins. Surface anisotropy, exchange interaction being different from in the core and incomplete coordination shell give rise to a variety of spin configuration near the surface and complex slain distributions within a particle. Base on Monte Carlo

Ultra-thin SiO 1ayer on Si (100) wafer have been fabricated by plasma oxidation at low temperature (250℃). Different take-off angle X-ray photoelectron spectroscopy (XPS) measurements reveal that the chemical composition in oxide layer is stoichiometric SiO and the SiO/Si interface is abrupt. The thickness of ultra-thin oxide layer can be estimated from both XPS and ellipsometry.

Ultrathin SiO2 layers on Si (100) wafers were prepared by plasma oxidation at a low temperature (250℃) . The analyses of X-ray photoelectron spectroscopy (XPS) and TEM reveal that the chemical composition of the oxide layer is stoichiometric SiO2 and the SiO2/Si interface is abrupt. The thickness of the ultrathin oxide layer obtained from XPS, capacitance-voltage (C-V) and ellipsometry measurements indicate a nonlinear time dependence. The high frequency C-V characterization of MOS structure shows that the fixed charge density in SiO2film is about 1011 cm-2. It is also shown that the strength of breakdown electrical field of SiO2 film with 6 nm thickness is of the order of 106 Vcm-1 . These properties of the ultrathin SiO2 layer ensure its application in silicon quantum devices.

Using a pulsed laser deposition technique, rhombohedral Pb(ZrTiO (PZT) thin films were fabricated on (001) LaAlO (LAO) single crystal substrates with LaNiO (LNO) buffer layer. X-ray diffraction (XRD) measurements on LNO/LAO and PZT/LNO/LAO revealed that the LNO and PZT films were highly c-axis oriented, consistent with the atomic force microscopy (AFM) surface morphologies.
