Engineering inorganic hybrid nanoparticles : tuning combination fashions of gold, platinum, and iron oxide
(2008)
Multistep colloidal chemical routes were employed to synthesize Pt/Au, Pt/iron oxide (IO), and Au/Pt/IO hybrid nanoparticles (NPs). The starting templates, Pt NPs, were synthesized by controlling the decomposition kinetics ...
An investigation of structure, magnetic properties and magnetoresistance of Ni films prepared by sputtering
(2004)
Ni films were deposited by magnetron sputtering with a relatively high deposition rate (0.5 nm/s). We have investigated the structure and magnetic properties of Ni films with different thicknesses. Strongly reduced ...
The preparation of Al2O3/M (Fe, Co, Ni) nanocomposites by mechanical alloying and the catalytic growth of carbon nanotubes
(2003)
Mechanical alloying was employed to produce Al2O3/M (M=Fe, Co, Ni) nanocomposites. It was found that high-energy mechanical milling could realize not only drastic refinement but also the well dispersion of catalyst precursors ...
Exchange bias and magnetization process of Co/CoO nanocomposite thin films
(2004)
Co/CoO nanocomposite thin films have been deposited by RF sputtering with different oxygen partial pressures in the working atmosphere. It has been found that the magnetic properties (exchange bias (EB), coercivity and ...
Microstructural evolution and its influence on the magnetic properties of CoFe2O4 powders during mechanical milling
(2006)
A high coercivity of up to 5.1 kOe was induced in a large-grained CoFe2O4 powder after milling for a short time (1.5 h). It was found that the initial grain (particle) size played an important role in the microstructural ...
Synthesis of boron nitride nanowires
(2002)
A chemical method has been developed for synthesizing boron nitride nanowires through the reaction of a mixture gas of nitrogen (N2) and ammonia (NH3) over nanoscale α-FeB particles at 1100 °C. Boron content in the product ...
Observation of clusters in Re60Fe30Al10 alloys and the associated magnetic properties
(2002)
Magnetic properties and microstructure of melt-spun ribbons of RE60Fe30Al10 alloys with RE = Nd, Sm, Dy, Gd and Y were studied in detail. High coercivity values in the range of MA m−1 were observed at low temperatures for ...
Large-scale preparation of carbon-encapsulated cobalt nanoparticles by the catalytic method
(2002)
With strategical selection of the water-soluble sodium chloride (NaCl) as the supporting material, we realized large-scale production of carbon-encapsulated cobalt nanoparticles with a productivity of almost 100%. The ...
