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 ... -
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 ... -
Influence of topology on the phase transition of a ferromagnetic metal
(2023)The topological ferromagnet CoS2 exhibits an anhysteretic, weakly first-order transition at the Curie temperature of 119.8 K with a tricritical point µ0Htcp at 0.034 T. Magnetic symmetry and the mixing of majority and ... -
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 ... -
Realization of Zero-Field Skyrmions in a Magnetic Tunnel Junction
(2023)Magnetic skyrmions are topologically protected noncollinear spin textures, which are regarded as promising information carriers for next-generation spintronic devices due to their small size and the low current density ... -
A simple experimental system to illustrate the nonlinear properties of a linear chain under compression.
(2020)A linear chain of spheres confined by a transverse harmonic potential experiences localized buckling under compression. We present simple experiments using gas bubbles in a liquid-filled tube to demonstrate this phenomenon. ... -
Structural, magnetic and electronic properties of L21 -ordered Ru2-xMn1+xAl Heusler alloy thin films
(2023)The cubic Heusler alloy Ru2–xMn1+xAl is grown in thin film form on MgO and MgAl2O4 substrates. It is a highly spin-polarised ferrimagnetic metal, with weak magnetocrystalline anisotropy. Although structurally and chemically ...
