Misorientations in [001] magnetite thin films studied by electron backscatter diffraction and magnetic force microscopy
(AMERICAN INSTITUTE OF PHYSICS, 2007)
Magnetite thin films grown on 001 oriented MgO substrates are analyzed by means of electron
backscatter diffraction EBSD analysis and magnetic force microscopy in applied fields. The EBSD
technique enables the ...
Photoluminescence from Liquid-Exfoliated WS<inf>2</inf> Monomers in Poly(Vinyl Alcohol) Polymer Composites
(2016)
While liquid phase exfoliation can be used to produce nanosheets stabilized in polymer solutions, very little is known about the resultant nanosheet size, thickness or monolayer content. Here we use semi-quantitative ...
Multiferroic properties of Bi-substituted Co2MnO4
(AIP, 2008)
Single phase polycrystalline samples of BixCo2-xMnO4 (x = 0.0, 0.1 and 0.3) were
synthesized by conventional solid state reaction. The crystallographic structure of all samples is
found to be cubic spinel (space group ...
Study of magnetoresistance of epitaxial magnetite films grown on vicinal MgO (100) substrate
(2005)
The magnetoresistance sMRd studies of magnetite thin films deposited on vicinal MgO substrates
show an enhanced MR along the miscut direction as compared to the direction perpendicular to it.
The MR anisotropy increases ...
Surface plasmon enhanced F?rster resonance energy transfer between the CdTe quantum dots
(2008)
Forster resonance energy transfer (FRET) between CdTe quantum dots (QDs) at nanoscale proximity to gold nanoparticle (Au NP) layers is investigated experimentally. We have observed the enhancement in the acceptor QDs' ...
Exfoliation and sensing application of 2D - materials
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)
In the past decade, graphene and layered material such as Transition metal dichalcogenides (TMDs) and Transition metal oxides (TMOs) have been investigated for their importance in several applications. For example, these ...
An XPS Study of the Oxidation of Reduced Ceria-Lanthana Nanocrystals
(Elsevier, 2011)
Detailed x-ray photoelectron spectroscopy (XPS) studies on the oxidation of an extensivley cleaned, reduced ceria-lanthana solid solution (12.5 mol% La to Ce) was performed. Uptake of oxygen during oxidation followed a ...
Spin-dependent transport in multifunctional tunnel junctions
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Spin-dependent tunnelling between ferromagnetic electrodes separated by insulating
oxide barriers has long attracted scientific and commercial interest. In the last
decade it became evident that the insulating layer was ...
Annealing effect on tunneling magnetoresistance in MgO-based magnetic tunnel junctions with FeMn exchange-bias layer
(2010)
MgO-based magnetic tunnel junctions were fabricated, with a thin pinned CoFeB layer in the unbalanced synthetic antiferromagnet part of the stack FeMn/CoFe/Ru/CoFeB. Inverted and normal tunneling magnetoresistance (TMR) ...
Tracking of an electron beam through the solar corona with LOFAR
(2018)
The Sun’s activity leads to bursts of radio emission, among other phenomena. An example is type-III radio bursts. They occur frequently and appear as short-lived structures rapidly drifting from high to low frequencies in ...
