While chiral magnets, metal-based magnetic multilayers, or Heusler compounds have been considered as the material workhorses in the field of skyrmionics, oxides are now emerging as promising alternatives, as they host special correlations between the spin–orbital–charge–lattice degrees of freedom and/or coupled ferroic order parameters. These interactions open new possibilities for practically exploiting skyrmionics. In this article, we review the recent advances in the observation and control…

Magnetic skyrmions: advances in physics and potential applications

Magnetic skyrmions are small swirling topological defects in the magnetization texture. Their stabilization and dynamics depend strongly on their topological properties. In most cases, they are

Antiferromagnetic half-skyrmions and bimerons at room temperature.

A family of topological antiferromagnetic spin textures in α-Fe2O3-an Earth-abundant oxide insulator-capped with a platinum overlayer are realized, which have characteristic sizes of the order of 100 nanometres and can be chemically controlled via precise tuning of the exchange and anisotropy, with pathways through which further scaling may be achieved.

Magnetic Skyrmion Materials.

The materials science and materials chemistry of magnetic skyrmions are described using the classification scheme of theskyrmion forming microscopic mechanisms, including the generation of emergent magnetic and electric field by statics and dynamics of skrymions and the inherent magnetoelectric effect.

Biskyrmion states and their current-driven motion in a layered manganite.

The real-space observation of a biskyrmion is shown, as defined by a molecular form of two bound skyrmions with the total topological charge of 2, realized under magnetic field applied normal to a thin plate of a bilayered manganite with centrosymmetric structure.

Observation of Skyrmions in a Multiferroic Material

It is found that the skyrmion can magnetically induce electric polarization in an insulating chiral-lattice magnet Cu2OSeO3 through Lorentz transmission electron microscopy and magnetic susceptibility measurements.

Interface-driven topological Hall effect in SrRuO3-SrIrO3 bilayer

It is established that the high-quality oxide interface enables us to tune the effective DM interaction; this can be a step toward future topological electronics.

The evolution of multiferroics

Materials with a coexistence of magnetic and ferroelectric order — multiferroics — provide an efficient route for the control of magnetism by electric fields. The study of multiferroics dates back to

Interfacial Dzyaloshinskii-Moriya interaction and chiral magnetic textures in a ferrimagnetic insulator

The interfacial Dzyaloshinskii-Moriya interaction (DMI) in multilayers of heavy metal and ferromagnetic metals enables the stabilization of novel chiral spin structures such as skyrmions. Magnetic

Real-space observation of ferroelectrically induced magnetic spin crystal in SrRuO3

This work has constructed an SrRuO3-PbTiO3 (Ferromagnetic – Ferroelectric) bilayer that exhibits features in the Hall Hysteresis previously attributed to a Topological Hall Effect, and Skyrmions, and confirms the role of an interfacial Dzyaloshinskii–Moriya interaction at the heart of the system.

Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction

It is shown that NV magnetometry, combined with the analysis method, provides a unique tool to investigate this previously inaccessible phenomenon and finds a Néel-type skyrmion whose chirality is not left-handed, contrary to preceding reports.
