Magnetic properties of fluffy Fe@α-Fe2O3 core-shell nanowires

: Novel fluffy Fe@α-Fe2O3 core-shell nanowires have been synthesized using the chemical reaction of ferrous sulfate and sodium borohydride, as well as the post-annealing process in air. The coercivity of the as-synthesized nanowires is above 684 Oe in the temperature range of 5 to 300 K, which is significantly higher than that of the bulk Fe (approximately 0.9 Oe). Through the annealing process...

Effect of solvents on morphology, magnetic and dielectric properties of (α-Fe2O3@SiO2) core-shell nanoparticles

Present work describes the formation of α-Fe2O3@SiO2 core shell structure by systematic layer by layer deposition of silica shell on core iron oxide nanoparticles prepared via various solvents. Sol-gel method has been used to synthesize magnetic core and the dielectric shell. The average crystallite size of iron oxide nanoparticles was calculated ∼20 nm by X-ray diffraction pattern. Morphologic...

Magnetic Properties of Ni0.3Fe0.7 Alloy Nanowires

The effect of length variation on the magnetic properties of NiFe alloy nanowires electrodeposited into the alumina template was investigated. The diameter (45±2.5 nm) and length (~ 1.9, 7.12, 8.3, 9.5 and 13.3 µm) of the nanowires were estimated from scanning electron microscopy images. Energy dispersive spectroscopy results showed Ni3Fe7 composition of the alloy nanowire...

Superparamagnetic Behavior of the Magnetic Hysteresis Loop in the Fe2O3@Pt Core-Shell Nanoparticles

Studies of the magnetization of Fe2O3@Pt nanoparticles at room temperature showed that there is superparamagnetic contribution with high saturation magnetization about 12.35(emu/g), and soft ferromagnetic contribution with narrow coercive field about 58(Oe). In this paper we fitted the hystersis loop of sample with Brillouin function that demonstrating existence of superparamagnetic phase. Tota...

Optical properties of crystalline-amorphous core-shell silicon nanowires.

The optical absorption in a nanowire heterostructure consisting of a crystalline silicon core surrounded by a conformal shell of amorphous silicon is studied. We show that they exhibit extremely high absorption of 95% at short wavelengths (λ < 550 nm) and a concomitant very low absorption of down to less than 2% at long wavelengths (λ > 780 nm). These results indicate that our nanowires do not ...
