Single Chiral Skyrmions in Ultrathin Magnetic Films
(MDPI, 2018-11-11)
The stability and sizes of chiral skyrmions in ultrathin magnetic films are calculated accounting for the isotropic exchange, Dzyaloshinskii-Moriya exchange interaction (DMI), and out-of-plane magnetic anisotropy within ...
Route to form skyrmions in soft magnetic films
(American Institute of Physics, 2019-08)
Magnetic skyrmions which are topologically nontrivial magnetization configurations have attracted much attention recently due to their potential applications in information recording and signal processing. Conventionally, ...
Higher order vortex gyrotropic modes in circular ferromagnetic nanodots
(Nature Publishing Group, 2014-04-25)
Magnetic vortex that consists of an in-plane curling magnetization configuration and a needle-like core region with out-of-plane magnetization is known to be the ground state of geometrically confined submicron soft magnetic ...
Microwave absorption properties of permalloy nanodots in the vortex and quasi-uniform magnetization states
(IOP Publishing, 2014-06-19)
When the in-plane bias magnetic field acting on a flat circular magnetic dot is smaller than the saturation field, there are two stable competing magnetization configurations of the dot: the vortex and the quasi-uniform ...
Nonlinear magnetic vortex dynamics in a circular nanodot excited by spin-polarized current
(Springer International Publishing, 2014-08-08)
We investigate analytically and numerically nonlinear vortex spin torque oscillator dynamics in a circular magnetic nanodot induced by a spin-polarized current perpendicular to the dot plane. We use a generalized nonlinear ...
How dry is dry? Molecular mobility in relation to thallus water content in a lichen
(Royal Society Of Chemistry, 2020-11-07)
The increasing demand for nanoscale magnetic devices requires development of 3D magnetic nanostructures. In this regard, focused electron beam induced deposition (FEBID) is a technique of choice for direct-writing of complex ...
The Bloch point 3D topological charge induced by the magnetostatic interaction.
(Nature Research, 2021-11-05)
[EN]A hedgehog or Bloch point is a point-like 3D magnetization configuration in a ferromagnet. Regardless of widely spread treatment of a Bloch point as a topological defect, its 3D topological charge has never been ...
Half-Hedgehog Spin Textures in sub-100 nm Soft Magnetic Nanodots
(Royal Society Of Chemistry, 2020-09-28)
Topologically non-trivial structures such as magnetic skyrmions are nanometric spin textures of outstanding potential for spintronic applications due to their unique features. It is well known that Neel skyrmions of definite ...
Magnetization Reversal Modes in Short Nanotubes with Chiral Vortex DomainWalls
(MDPI, 2018-01-10)
Micromagnetic simulations of magnetization reversal were performed for magnetic nanotubes of a finite length, L, equal to 1 and 2 mum, 50 and 100 nm radii, R, and uniaxial anisotropy with "easy axis" parallel to the tube ...
