Stability and capping of magnetite ultra-thin films
(2014)
Ultrathin films of Fe3O4 have been grown epitaxially on nearly lattice matched MgO(001). The stability of
4 nm thick films in ambient air and under annealing in an oxygen atmosphere at 200◦C has been studied. By
magneto ...
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 ...
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 ...
Hybrid DFT calculation of 57Fe NMR resonances and orbital order in magnetite
(2014)
The crystal structure and charge and orbital order of magnetite below the Verwey temperature are calculated
using a first-principles hybrid density functional theory (DFT) method. The initial atomic positions in ...
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 ...
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. ...
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 ...
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 ...
