RKKY interaction between adsorbed magnetic impurities in graphene: symmetry and strain effects
(2013)
The growing interest in carbon-based spintronics has stimulated a number of recent theoretical studies on
the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in graphene, with the aim of determining the most
energetically ...
Magnetic Forces in Paramagnetic Fluids
(2022)
An overview of the effect of a magnetic field gradient on fluids with linear magnetic susceptibilities is given. It is shown that two commonly encountered expressions, the magnetic field gradient force and the concentration ...
Large magnetoresistance in few layer graphene stacks with current perpendicular to plane geometry
(2012)
Large magnetoresistance (MR) effect of few layers graphene between two non-magnetic metal electrodes with current perpendicular to graphene plane was studied. A non-saturation and anisotropic MR with the value over 60% at ...
High-Speed Chromatic Dispersion Monitoring of a Two-Channel WDM System using a single TPA Microcavity
(IEEE Lasers and Electro-Optics Society, 2008)
Chromatic dispersion monitoring of two 160Gb/s wavelength channels using a TPA
Microcavity is presented. As the microcavity exhibits a wavelength resonance characteristic, a
single device could monitor a number of different ...
Effect of epitaxial strain on the spontaneous polarization of thin film ferroelectrics
(American Physical Society, 2005)
Epitaxial strain can substantially enhance the spontaneous polarizations and Curie temperatures of ferroelectric thin films compared to the corresponding bulk materials. In this Letter we use first principles calculations ...
On the conservation of the angular momentum in ultrafast spin dynamics
(2021)
The total angular momentum of a close system is a conserved quantity, which should remain constant in time for any excitation experiment once the pumping signal has extinguished. Such conservation, however, is never satisfied ...
CALPHAD-assisted development of in-situ nanocrystallised melt-spun Co-Fe-B alloy with high Bs (1.57 T)
(2021)
A thermodynamics-based approach, Calculation of Phase Diagram (CALPHAD), combined with topological instability parameters are proposed and experimentally evaluated, in order to optimise in-situ nanocrystallisation of rapidly ...
Mechanical Characterisation of Printed Nanosheet Network Thin Films
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
The response of materials to applied stress and the resulting deformation is a fundamental
cornerstone of condensed matter physics and materials research. From exciting new prospects such
as the conductive nanosheet ...
All-printed capacitors from graphene-BN-graphene nanosheet heterostructures
(2016)
This work aims to develop methodologies to print pinhole-free, vertically stacked heterostructures by sequential deposition of conductive graphene and dielectric h-BN nanosheet networks. We achieve this using a combination ...
