A theory on skyrmion size

open access: yes, 2018
A magnetic skyrmion is a topological object consisting of a skyrmion core, an outer domain, and a wall that separates the skyrmion core from the outer domain.

Structural transition of skyrmion quasiparticles under compression

open access: yes, 2022
The competition between external drives and interparticle interactions are important for the static and dynamic properties of topological quasiparticles in confined geometries. Here, we study the dynamics of particlelike skyrmions under a current-induced

Aluminum‐Substituted Yttrium Iron Garnet Films With Perpendicular Anisotropy Grown on Silicon by Sputtering

open access: yesAdvanced Electronic Materials, EarlyView.
Ultrathin Al‐substituted YIG films with perpendicular magnetic anisotropy are sputter‐grown directly on Si/SiOx using an ultrathin AlOx buffer layer. Al diffusion reduces the saturation magnetization and stabilizes PMA via magnetoelastic effects. Pt/Al:YIG bilayers exhibit strong spin Hall magnetoresistance and efficient spin–orbit torque switching ...

Stability and metastability of skyrmions in thin lamellae of Cu_{2}OSeO_{3}

open access: yesPhysical Review Research, 2020
We report small-angle x-ray scattering measurements of the skyrmion lattice in two 200-nm-thick Cu_{2}OSeO_{3} lamellae aligned with the applied magnetic field parallel to the out of plane [110] or [100] crystallographic directions. Our measurements show

Skyrmion Dynamics for Spintronic Devices [PDF]

open access: yes, 2013
Magnetic Skyrmion is a topological stable, particle-like spin texture. Its unique proper-ties such as curren-driven motion and topological protected make it to be a candidate forfuture spintronic devices.

Field‐Programable Dynamics in a Soft Magnetic Actuator Enabling True Random Number Generation and Reservoir Computing

open access: yesAdvanced Intelligent Systems, EarlyView.
Complex dynamics, often avoided in electromechanical design, can enhance soft robotics. We develop durable magnetic soft actuators operating in tunable dynamic regimes, enabling random number generation, stochastic computing, and time‐series prediction.

Simulation-trained machine learning models for Lorentz transmission electron microscopy

open access: yesAPL Machine Learning
Understanding the collective behavior of complex spin textures, such as lattices of magnetic skyrmions, is of fundamental importance for exploring and controlling the emergent ordering of these spin textures and inducing phase transitions.

Skyrmion number for a generalized vector Poincaré beam

open access: yesКомпьютерная оптика
We investigate two initial vector Poincaré-type light fields that can be treated as optical skyrmions – topological quasiparticles. For such fields, explicit expressions are obtained for the components of a 3D-vector skyrmionic field in the initial plane

The influence of the edge effect on the skyrmion generation in a magnetic nanotrack

open access: yes, 2017
Magnetic skyrmions might be used for building next-generation nanomagnetic and spintronic devices, as they have several perspective properties, such as topologically protected stability, nanoscale size, and ultra-low depinning current density.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

open access: yesAdvanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired
