Sub-picosecond exchange-relaxation in the compensated ferrimagnet Mn2RuxGa
(2021)
We study the demagnetization dynamics of the fully compensated half-metallic ferrimagnet Mn2RuxGa. While the two antiferromagnetically coupled sublattices are both composed of manganese, they exhibit different temperature ...

RKKY interaction between extended magnetic defect lines in graphene
(2014)
Of fundamental interest in the field of spintronics is the mechanism of indirect exchange coupling between
magnetic impurities embedded in metallic hosts. A range of physical features, such as magnetotransport and
overall ...
Reversible hydrogen control of antiferromagnetic anisotropy in α-Fe2O3
(2021)
Antiferromagnetic insulators are a ubiquitous class of magnetic materials, holding the promise of low-dissipation spin-based computing devices that can display ultra-fast switching and are robust against stray fields. ...
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 ...
Pressure Dependent Mechanical Properties of Thin Films under Uniaxial Strain via the Layer Compression Test
(2023)
Amorphous materials can exhibit strong nonlinear mechanical properties in comparison to crystalline metals and ceramics, largely due to their non equilibrium state which depends on the means of sample preparation history. ...
