Phase-diagram of condensed and isolated skyrmions in chiral magnetic films
Communications PhysicsSkyrmions in chiral magnetic films exist either in the isolated phase, confined within the sample, or the condensed phase, occupying it entirely. The stability of magnetic structures in generic perpendicularly magnetized chiral magnetic films is fully ...

, 2014 Spin transfer torque (STT) affords magnetic nanodevices the potential to act as memory, computing, and microwave elements operating at ultra-low currents and at a low energy cost. Spin transfer torque is not only effective in manipulating well-known magnetic structures, such as domain walls and vortices, but can also nucleate previously unattainable ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
Laser &Photonics Reviews, EarlyView.The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Current-induced skyrmion generation and dynamics in symmetric bilayers
Nature Communications, 2017 The creation of practical devices based on magnetic skyrmions depends on the development of methods to create and control stable individual skyrmions. Here, the authors present a bilayer device that uses dipolar interactions to stabilize skyrmions that ...

Edge instabilities and skyrmion creation in magnetic layers
, 2016 We study both analytically and numerically the edge of two-dimensional ferromagnets with Dzyaloshinskii-Moriya (DM) interactions, considering both chiral magnets and magnets with interface-induced DM interactions.

Non‐reciprocal spin excitations across the skyrmion–paramagnetic phase transition in MnSi
Journal of Applied Crystallography, EarlyView.Inelastic neutron scattering shows that the non‐reciprocal nature of the magnons in the skyrmion phase of MnSi is maintained for high temperatures well beyond the skyrmion–paramagnetic phase transition.The magnetic excitations of the skyrmion lattice in MnSi comprise a multitude of individual modes, which are non‐reciprocal and thereby propagate ...

Crystallization of magnetic skyrmions in MnSi investigated by neutron spin echo spectroscopy
Physical Review Research, 2020 We performed neutron resonance spin echo measurements on MnSi to investigate how the magnetic skyrmions crystalize into a lattice on cooling in a magnetic field.

Thermally assisted skyrmions creation in Pt/Co/Ta multilayer films
, 2018 N\'eel-type magnetic skyrmions in multilayer films have attracted significant amount of attention recently for their stability at room temperature and capability of motion driven by a low-density electrical current, which can be potentially applied to ...
