Fabrication and characterization of Fe3O4/perlite, Fe3O4/perlite@SiO2, and Fe3O4/perlite@SiO2@sulfanilamide magnetic nanomaterials

Applied Physics A: Materials Science and Processing, 2022
Abstract In this study, the fabrication of perlite-supported Fe3O4 (Fe3O4/perlite), SiO2-coated Fe3O4/perlite (Fe3O4/perlite@SiO2), and sulfanilamide-modified Fe3O4/perlite@SiO2 (Fe3O4/perlite@SiO2@sulfanilamide) magnetic nanomaterials and their characterization by various spectroscopic techniques were presented.

Magnetic and electronic properties of Fe3O4/PtSe2/Fe3O4 junctions

Materials Today: Proceedings, 2022
Abstract Two-dimensional (2D) materials with single or a few-atomic layers have attracted significant attention from the scientific community due to their transport properties and potential for technological applications. A variety of 2D materials beyond graphene with different bandgaps have been synthesized in recent years.

Magnetoresistance of Fe3O4/Au/Fe3O4 and Fe3O4/Au/Fe spin-valve structures

Journal of Magnetism and Magnetic Materials, 2004
Abstract A detailed study of the in-plane magnetotransport properties of spin valves with one and two Fe 3 O 4 electrodes is presented. Fe 3 O 4 /Au/Fe 3 O 4 spin valves exhibit a clear anisotropic magnetoresistance in small magnetic fields but no giant magnetoresistance (GMR).

Mechanisms for the Oxidation of Fe3O4

Nature, 1970
WE have published results1 of a study of the kinetics of the oxidation of a sample of Fe3O4 consisting of submicron crystals almost perfectly cubic and almost uniform in size2. In agreement with Egger and W. F.3 and W. F.4,5, it was found that the reaction was single phase topotactic (Fe3O4→Fe3−xO4→γ-Fe2O3).

On the magnetic aggregation of Fe3O4 nanoparticles

Computer Methods and Programs in Biomedicine, 2021
Background and objective In-vivo MRI-guided drug delivery concept is a personalized technique towards cancer treatment. A major bottleneck of this method, is the weak magnetic response of nanoparticles. A crucial improvement is the usage of paramagnetic nanoparticles aggregates since they can easier manipulated in human arteries than isolated particles.

Characterization for strontium titinate/Fe3O4 and TiN/Fe3O4 interfaces

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2002
The interface formation between different thicknesses of strontium titanate (SrTiO3) or titanium nitride (TiN) with a 2000 Å Fe3O4 film is studied using x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD). Our results show that the deposition of 10–50 Å of TiN results in an immediate and substantial removal of oxygen from ...

Magnetoresistance effect in Ag–Fe3O4 and Al–Fe3O4 composite films

Journal of Applied Physics, 2003
The Agx–(Fe3O4)1−x and Agx–(Fe3O4)1−x composite films were prepared by dc sputtering on Si(100) substrates. The x-ray diffraction results show that the films contain essentially only the cubic inverse spinal phase from Fe3O4 and face-centered cubic phase from Ag or Al.

Polysorbate Stabilised Fe3O4 and Fe3O4@Au Nanoparticle Synthesis and Characterisation

Materials Today: Proceedings, 2015
Polysorbate (tween) stabilised iron oxide and gold coated iron oxide nanoparticles were synthesised using the high-temperature solution phase reaction of iron(III) acetylacetate, Fe(acac)3, with 1,2-hexadecanediol and long chain alcohols. FT-IR analysis confirmed the presence of the surfactants on the nanoparticles, while the size and shape of the ...
