Large Reversible Plasmon Shift with Au Nanodisc Dimers on Thin film VO2
(2022)By coupling Au dimer nanostructures to an underlying thin film of phase change material, vanadium dioxide, significant shifts in the plasmonic scattering spectra are observed, allowing for dynamic tuning within the visible ... -
Direct laser writing of submicron photonic arrays for vapor-responsive sensing
(2022)A two photon polymerization technique was used to fabricate 2D photonic crystals based on a vapor-responsive hydrogel. By testing their vapor sensing performance, these photonic arrays were found to exhibit dynamic stimulus ... -
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 ... -
Evaporation of water and urea solution in a magnetic field; the role of nuclear isomers
(2023)Hypothesis Ortho and para water are the two nuclear isomers where the hydrogen protons align to give a total nuclear spin of 1 or 0. The equilibrium ratio of 3:1 is established slowly in freshly evaporated water vapour ... -
Au4Mn: A localized ferromagnet with strong spin-orbit coupling, long-rangeferromagnetic exchange, and high Curie temperature
(2022)Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal Au 4 Mn with a Curie temperature of ... -
Electrical detection of magnetic skyrmyons in a magnetic tunnel junction
(2022)Magnetic skyrmions are promising information carriers for dense and energy-efficient information storage owing to their small size, low driving-current density, and topological stability. Electrical detection of skyrmions ... -
Deformation and necking of liquid droplets in a magnetic field.
(2022)Pendant droplets of water and paramagnetic solutions are studied in the presence of uniform and nonuniform magnetic fields produced by small permanent magnet arrays, both in static conditions and during dynamic pinch-off. ... -
Noncollinear ferrimagnetism and anomalous Hall effects in Mn4N thin films
(2022)Thin films of Mn 4 N and related ternary metallic perovskites with perpendicular anisotropy are interesting for spintronics, but their magnetic structures differ from the triangular ferrimagnetism of the bulk. A ... -
Rare-earth-free noncollinear metallic ferrimagnets Mn4-xZxN with compensation at room temperature
(2022)Compensated ferrimagnets show no net magnetization like antiferromagnets, but their transport and magneto-optic properties resemble those of ferromagnets, thereby creating opportunities for applications in high-frequency ... -
Metallic Nitride and Carbide Perovskites: History and Prospects
(2022)Energy-level diagrams for cubic metallic Fe4N and Mn4N were proposed by Goodenough in the late 1960s. Fe4N is ferromagnetic, but Mn4N is ferrimagnetic with a large moment on Mnc at the cube corner site and a much smaller ... -
Stability of Mn2RuxGa-based Multilayer Stacks, Gwenaël Atcheson, Katarzyna Siewierska, J. M. D. Coey, Karsten Rode, Plamen Stamenov
(2022)Perpendicular heterostructures based on a ferrimagnetic Mn2RuxGa (MRG) layer and a ferromagnetic Co/Pt multilayer were examined to understand the effects of different spacer layers (V, Mo, Hf, HfOx and TiN) on the interfaces ... -
Single-pulse all-optical switching in amorphous DyxCo1-x and TbxCo1-x
(2022)Repeated uniform switching of the magnetization of thin films of ferrimagnetic amorphous Gdx(FeCo)1−x in response to single fast laser pulses is well established. Here, we report unusual toggle switching in thin films of ... -
The growth of high-crystalline quality M n 2 Au (110) thin films
(2022)Mn2Au is a bimetallic antiferromagnetic with an extraordinarily high Néel temperature of 1600 K. Mn2Au has also been found to demonstrate Néel-order spin–orbit torque, allowing for electrical switching of the antiferromagnetic ... -
Buckling of a tilted line of confined hard spheres
(2022)A linear chain of hard spheres confined in a transverse harmonic potential is unstable and buckles, if tilted beyond some critical angle. We examine this symmetry breaking using a computational model that was previously ... -
Tunable plasmonics with Au nanoparticles coupled to thin film vanadium dioxide
(2022)The development of active devices featuring dynamic tunable plasmonic resonances is vital for wide implementation in many optoelectronic devices. By coupling plasmonic nanoparticles to an underlying thin film of phase ... -
Electrically Driven Reprogrammable Vanadium Dioxide Metasurface Using Binary Control for Broadband Beam Steering
(2022)Resonant optical phased arrays are a promising way to reach fully reconfigurable metasurfaces in the optical and near-infrared (NIR) regimes with low energy consumption, low footprint, and high reliability. Continuously ... -
Association of perceptions of artificial light-at-night, light-emitting device usage and environmental noise
(2022)Exposure to artificial light-at-night (ALAN) is increasing globally, and there are concerns around how ALAN may impact sleep, psychological and physical health. However, there is a lack of evidence in the literature on how ... -
Liquid Processing of Interfacially Grown Iron-Oxide Flowers into 2D-Platelets Yields Lithium-Ion Battery Anodes with Capacities of Twice the Theoretical Value
(2022)Iron oxide (Fe2O3) is an abundant and potentially low-cost material for fabricating lithium-ion battery anodes. Here, the growth of α-Fe2O3 nano-flowers at an electrified liquid–liquid interface is demonstrated. Sonication ... -
Liquid-Phase Exfoliation of Nonlayered Non-Van-Der-Waals Crystals into Nanoplatelets
(2023)For nearly 15 years, researchers have been using liquid-phase exfoliation (LPE) to produce 2D nanosheets from layered crystals. This has yielded multiple 2D materials in a solution-processable form whose utility has been ... -
Toward exact predictions of spin-phonon relaxation times: An ab initio implementation of open quantum systems theory
