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 ...
Quantum theory of multimode polariton condensation
(2014)
We develop a theory for the dynamics of the density matrix describing a multimode polariton condensate.
In such a condensate several single-particle orbitals become highly occupied, due to stimulated scattering from
reservoirs ...
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 ...
Imaging and identification of point defects in PtTe2
(2021)
The properties and performance of two-dimensional (2D) materials can be greatly affected by point defects. PtTe2, a 2D material
that belongs to the group 10 transition metal dichalcogenides, is a type-II Dirac semimetal, ...
Superlubric Sliding of Graphene Auto-Kirigami with Interfaces Containing Self-Assembled Stripe-Pattern Adsorbates
(2024)
Van der Waals heterostructures formed by stacked 2D materials show exceptional electronic, mechanical, and optical properties. Superlubricity, a condition where atomically flat, incommensurate planes of atoms results in ...
