Magnetic order and magnetotransport in half-metallic ferrimagnetic MnyRuxGa thin films
(2021)
The ruthenium content of half-metallic Mn2RuxGa thin films, with a biaxially strained inverse Heusler structure, controls the ferrimagnetism that determines their magnetic and electronic properties. An extensive study of ...
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 ...
Ultrafast Double Pulse All-Optical Reswitching of a Ferrimagnet
(2021)
All-optical reswitching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effect of a second 200 fs, 800 nm laser pulse ...
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 ...
Pauli paramagnetism of cubic V3Al, CrVTiAl, and related 18-electron Heusler compounds with a group-13 element
(2021)
Calculations suggest that ordered Heusler alloys with 18 valance electrons could exhibit a variety of unusual electronic and magnetic states that are absent in the constituent elements. They include magnetic semiconductors, ...
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 ...
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. ...
