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 ...
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 ...
Magnetic control over the fractal dimension of supramolecular rod networks
(2021)
Controlling supramolecular polymerization is of fundamental importance to create advanced materials and devices. Here we show that the thermodynamic equilibrium of Gd3+-bearing supramolecular rod networks is shifted ...
Exfoliation of hematite: Morphological, structural and magnetic investigations
(2022)
Three natural specimens of hematite are characterized using X-ray diffraction, magnetometry, IR/Raman and Mössbauer spectroscopy, with focus on the Morin transition. All are exfoliated by grinding and prolonged sonication ...
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 ...
Imaging domains in a zero-moment half-metal
(2019)
We have a choice of methods for examining domains at the surface of a ferromagnet that depend on probing the stray field distribution, but these methods do not work in antiferromagnets or compensated ferrimagnets, which ...
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 reversal and pinning in a perpendicular zero-moment half-metal
(2021)
Compensated ferrimagnets are promising materials for fast spintronic applications based on domain-wall motion as they combine the favorable properties of ferromagnets and antiferromagnets. They inherit from antiferromagnets ...
