چکیده
Magnetic nanoparticles embedded into semiconductors have current perspectives for use in semiconducting spintronics. In this work, 40 keV Fe+ ions were implanted high fluences of (0.5 ÷ 1.5) × 1017 ion/cm2 an oxide semiconductor and single-crystalline TiO2 plates rutile structure with (100) or (001) face orientations. Microstructure, elemental-phase composition, magnetic properties the Fe-ion-implanted studied by scanning transmission electron microscopies (SEM TEM), X-ray photoelectron (XPS) Rutherford backscattering (RBS) spectroscopies, as well vibrating-sample magnetometry (VSM). The high-fluence ion implantation results formation metallic iron beneath irradiated surface rutile. induced ferromagnetism observed two- four-fold anisotropy are associated endotaxial growth Fe oriented along crystallographic axes TiO2.

Cluster synthesis of monodisperse rutile-TiO2 nanoparticles and dielectric TiO2-vinylidene fluoride oligomer nanocomposites.
The embedding of oxide nanoparticles in polymer matrices produces a greatly enhanced dielectric response by combining the high dielectric strength and low loss of suitable host polymers with the high electric polarizability of nanoparticles. The fabrication of oxide-polymer nanocomposites with well-controlled distributions of nanoparticles is, however, challenging due to the thermodynamic and k...
متن کاملHalide ion-mediated growth of single crystalline Fe nanoparticles.
We report a facile halide ion (Cl(-) or Br(-)) mediated synthesis of Fe nanoparticles (NPs) by thermal decomposition of Fe(CO)5. The NP structure is controlled to be either amorphous (in the absence of halide ions) or single crystalline bcc (in the presence of halide ions). Through systematic investigation on the synthetic conditions, we have confirmed that the formation of bcc-Fe NPs is facili...

متن کاملSynthesis and Characterization of Bowl-Like Single-Crystalline BaTiO3 Nanoparticles
Novel bowl-like single-crystalline BaTiO(3) nanoparticles were synthesized by a simple hydrothermal method using Ba(OH)(2)·8H(2)O and TiO(2) as precursors. The as-prepared products were characterized by XRD, Raman spectroscopy, SEM and TEM. The results show that the bowl-like BaTiO(3) nanoparticles are single-crystalline and have a size about 100-200 nm in diameter. Local piezoresponse force me...
متن کاملSolution-phase synthesis of single-crystalline iron phosphide nanorods/nanowires.
A solution-phase route for the preparation of single-crystalline iron phosphide nanorods and nanowires is reported. We have shown that the mixture of trioctylphosphine oxide (TOPO) and trioctylphosphine (TOP), which are commonly used as the solvents for semiconductor nanocrystal synthesis, is not entirely inert. In the current process, TOP, serving as phosphor source, reacts with Fe precursors ...
