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 ... -
Conducting mechanism in the epitaxial p-type transparent conducting oxide Cr2O3:Mg
(2015)Epitaxial p -type transparent conducting oxide (TCO) Cr 2 O 3 :Mg was grown by electron-beam evaporation in a molecular beam epitaxy system on c -plane sapphire. The influence of Mg dopants and the oxygen partial ... -
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. ... -
Deterministic multi-level spin orbit torque switching using focused He+ ion beam irradiation
(2023)He+ ion irradiation is used to pattern multiple areas of Pt/Co/W films with different irradiation doses in Hall bars. The resulting perpendicular magnetic anisotropy landscape enables selective multilevel current-induced ... -
"Effective Electrode Length Enhances Electrical Activation of Nanowire Networks: Experiment and Simulation"
(2014)Networks comprised of randomly oriented overlapping nanowires offer the possibility of simple fabrication on a variety of substrates, in contrast with the precise placement required for devices with single or aligned ... -
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 ... -
Electrical detection of spin pumping in van der Waals ferromagnetic Cr2Ge2Te6 with low magnetic damping
(2023)The discovery of magnetic order in atomically-thin van der Waals materials has strengthened the alliance between spintronics and two-dimensional materials. An important use of magnetic two-dimensional materials in spintronic ... -
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 ... -
Ferromagnetic resonance damping mechanisms in CoFeB thin films with Cr substitution
(2023)The substitution of iron atoms by chromium in CoFeB films has been proposed to reduce the critical current density Jc for current-driven magnetization switching in spin transfer torque devices by reducing its magnetization. ... -
A fully compensated ferrimagnetic half metal Co1-xCrxS2 with Curie temperature above room temperature
(2023)Fully compensated ferrimagnetic half metals have attracted great attention in spintronics. Unlike many previous calculations based on hypothetical ordered alloys, here we look for existing solid solution series taking as ... -
Magnetic Field Enhancement of Water Evaporation in Confined Spaces
(2023)Water is studied in confined environments where it evaporates into its own vapor. Simultaneous experiments are conducted for 0.4–0.5 µL droplets confined at the center of 54 mm long microchannels with a cross section of ... -
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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
