Antiferromagnetic Skyrmion: Stability, Creation and Manipulation. Xichao Zhang et al (2016), Scientific Reports http://dx.doi.org/10.1038/srep24795
Magnetic skyrmions are particle-like topological excitations in ferromagnets, which have the topo-logical number Q = ± 1, and hence show the skyrmion Hall effect (SkHE) due to the Magnus force effect originating from the topology. Here, we propose the counterpart of the magnetic skyrmion in the antiferromagnetic (AFM) system, that is, the AFM skyrmion, which is topologically protected but without showing the SkHE. Two approaches for creating the AFM skyrmion have been described based on micromagnetic lattice simulations: (i) by injecting a vertical spin-polarized current to a nanodisk with the AFM ground state; (ii) by converting an AFM domain-wall pair in a nanowire junction. It is demonstrated that the AFM skyrmion, driven by the spin-polarized current, can move straightly over long distance, benefiting from the absence of the SkHE. Our results will open a new strategy on designing the novel spintronic devices based on AFM materials.

The movie shows sequential switching of the skyrmion driven by the series of magnetic field pulses with amplitude of B = 3 Tesla and Gaussian pulse duration of 15 ps with alternating polar angles 45 and 135 degrees.
The simulated domain has square shape of 100 x 100 x 3 spins, the material parameters J=5 meV, D/J=0.16, K/J=0.1, damping=0.1 and open boundary conditions.

Magnetic skyrmion logic gates: conversion, duplication and merging of skyrmions. Xichao Zhang et al (2015), Scientific Reports http://www.nature.com/srep/2015/150324/srep09400/full/srep09400.html
Magnetic skyrmions, which are topological particle-like excitations in ferromagnets, have attracted a lot of attention recently. Skyrmionics is an attempt to use magnetic skyrmions as information carriers in next generation spintronic devices. Proposals of manipulations and operations of skyrmions are highly desired. Here, we show that the conversion, duplication and merging of isolated skyrmions with different chirality and topology are possible all in one system. We also demonstrate the conversion of a skyrmion into another form of a skyrmion, i.e., a bimeron. We design spin logic gates such as the AND and OR gates based on manipulations of skyrmions. These results provide important guidelines for utilizing the topology of nanoscale spin textures as information carriers in novel magnetic sensors and spin logic devices.

Universal helimagnon and skyrmion excitations in metallic, semiconducting and insulating chiral magnets. T. Schwarze et al (2015), Nature Materials http://dx.doi.org/10.1038/nmat4223
Nearly seven decades of research on microwave excitations of magnetic materials have led to a wide range of applications in electronics. The recent discovery of topological spin solitons in chiral magnets, so-called skyrmions, promises high-frequency devices that exploit the exceptional emergent electrodynamics of these compounds. Therefore, an accurate and unified quantitative account of their resonant response is key. Here, we report all-electrical spectroscopy of the collective spin excitations in the metallic, semiconducting and insulating chiral magnets MnSi, Fe1−xCoxSi and Cu2OSeO3, respectively, using broadband coplanar waveguides. By taking into account dipolar interactions, we achieve a precise quantitative modelling across the entire magnetic phase diagrams using two material-specific parameters that quantify the chiral and the critical field energy. The universal behaviour sets the stage for purpose-designed applications based on the resonant response of chiral magnets with tailored electric conductivity and an unprecedented freedom for an integration with electronics.

Skyrmion
In particle theory, the skyrmion (/ˈskɜːrmi.ɒn/) is a hypothetical particle related originally to baryons. It was described by Tony Skyrme in 1962 and consists of a quantum superposition of baryons and resonance states. It could be predicted from some nuclear matter properties.
Skyrmions as topological objects are important in solid state physics, especially in the emerging technology of spintronics. A two-dimensional magnetic skyrmion, as a topological object, is formed, e.g., from a 3D effective-spin "hedgehog" (in the field of micromagnetics: out of a so-called "Bloch point" singularity of homotopy degree +1) by a stereographic projection, whereby the positive north-pole spin is mapped onto a far-off edge circle of a 2D-disk, while the negative south-pole spin is mapped onto the center of the disk.
Mathematical definition
In field theory, skyrmions are homotopically non-trivial classical solutions of a nonlinear sigma model with a non-trivial target manifold topology – hence, they are topological solitons. An example occurs in chiral models of mesons, where the target manifold is a homogeneous space of the structure group

Edit Public Technologies 21 Sep 2016
Department of Energy's (DOE's) Argonne National Laboratory, scientists noticed that magnetic skyrmions - small electrically uncharged circular structures with a spiraling magnetic pattern - do get deflected by an applied current. Although skyrmions do not have electric charge, they do have what researchers call 'topological charge,' and it is this charge that causes their deflection....

Skyrmions à la carte
Edit Science Daily 03 Jun 2016
Magnetic vortices -- so-called skyrmions -- are stable, can have a diameter of just a few nanometres, and can be moved efficiently by electrical currents ... However, until very recently, the only materials known to exhibit skyrmions did so at extremely low temperatures. Scientists have predicted that skyrmions can also be realized for application at ......
Imaging the dynamics of skyrmion clusters [Applied Physical Sciences]>
Edit PNAS 03 May 2016
Magnetic skyrmion is a nanosized magnetic whirl with nontrivial topology, which is highly relevant for applications on future memory devices. To enable the applications, theoretical efforts have been made to understand the dynamics of individual skyrmions in magnetic nanostructures. However, directly imaging the evolution of highly geometrically confined individual skyrmions... ....

Scientists divide magnetic vortices into collectivists and individualists
Edit Science Daily 01 Apr 2016
In manganese monosilicide, microscopic magnetic vortices -- skyrmions -- may behave as 'collectivists' or 'individuals,' i.e. they are able to create a single structure, or they can also split up individually. Studying the behavior of skyrmions will help to create unique quantum devices based on new physical principles ... ....
