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).

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 ...

Electrochemical-enhanced MoS2/Fe3O4 peroxymonosulfate (E/ MoS2/Fe3O4/PMS) for degradation of sulfamerazine

Chemosphere, 2022
Seeking effective methods to degrade organic pollutants has always been a hot research field. In this work, MoS2/Fe3O4 catalyst was synthesized by hydrothermal method with MoS2 as carrier to construct an advanced oxidation system of electrochemical enhanced MoS2/Fe3O4-activated peroxymonosulfate (E/MoS2/Fe3O4/PMS). The materials were characterized by X-

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 ...
