Antiferromagnetic single-layer spin-orbit torque oscillators
(2019)
We show how a charge current through a single antiferromagnetic layer can excite and control self-oscillations. Sustained oscillations with tunable amplitudes and frequencies are possible in a variety of geometries using ...
Optics In Ireland
(Optical Society of America, 2018)
This feature issue provides a snapshot of some of the applied optics and photonics related research and development activities currently taking place across Ireland. The issue contains some thirty papers, including ...
The Electro-Optical Performance of Silver Nanowire Networks
(2019)
Networks of metallic nanowires have the potential to meet the needs of next-generation device technologies that require flexible transparent conductors. At present, there does not exist a first principles model capable of ...
Spin transfer torque in Mn3Ga -based ferrimagnetic tunnel junctions from first principles
(2021)
We report on first-principles calculations of spin-transfer torque (STT) in epitaxial magnetic tunnel junctions (MTJs) based on ferrimagnetic tetragonal Mn3Ga electrodes, both as analyzer in a Fe/MgO stack, and also in an ...
Neutron Imaging of Paramagnetic Ions: Electrosorption by Carbon Aerogels and Macroscopic Magnetic Forces
(2021)
The electrosorption of Gd3+ ions from an aqueous 70 mM Gd(NO3)3 solution in monolithic carbon aerogel electrodes was recorded by dynamic neutron imaging. The aerogels have a bimodal pore size distribution consisting of ...
Detection of the Faraday Chiral Anisotropy
(2021)
Being the intimate connection between chirality and magnetism, magneto-chiral anisotropies (MChA) - featuring non-reciprocal optical responses in chiral systems depending on the relative direction of the magnetic field B ...
