Spintronics via non-axisymmetric chiral skyrmions

TL;DR

This paper explores the behavior of non-axisymmetric chiral skyrmions in confined helimagnets under magnetic fields, proposing their potential use in nanoelectronics as an alternative to traditional skyrmions.

Contribution

It introduces the concept of non-axisymmetric skyrmions driven by magnetic fields and discusses their potential application in nanoelectronic devices.

Findings

Non-axisymmetric skyrmions evolve peculiarly under magnetic fields.

These skyrmions can serve as effective alternatives in nanoelectronic devices.

The study provides micromagnetic calculations supporting these behaviors.

Abstract

Micromagnetic calculations demonstrate a peculiar evolution of non-axisymmetric skyrmions driven by an applied magnetic field in confined helimagnets with longitudinal modulations. We argue that these specific solitonic states can be employed in nanoelectronic devices as an effective alternative to the common axisymmetric skyrmions which occur in magnetically saturated states.
