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 ...
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 ...
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. ...
Broadband saturable absorption and exciton-exciton annihilation in MoSe2 composite thin films
(2019)
Polyvinyl alcohol (PVA) was utilized as a matrix to host two-dimensional (2D)
liquid-phase-exfoliated MoSe2 nanosheets. These 2D MoSe2/PVA composite thin films were
experimentally proven to be preferable for efficient ...
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. ...
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 ...
