# Light-induced anisotropic skyrmion and stripe phases in a Rashba ferromagnet

## TL;DR

This paper explores how off-resonant light can be used to control magnetic phases in Rashba ferromagnets, enabling stabilization and manipulation of skyrmions and stripe phases through induced anisotropy of the Dzyaloshinskii-Moriya interaction.

## Contribution

It introduces a theoretical and numerical framework showing how linearly polarized off-resonant light induces anisotropic DMI, stabilizing novel magnetic phases and controlling skyrmion properties.

## Key findings

- Off-resonant light induces strong anisotropy in DMI.
- Stabilization of noncollinear magnetic phases.
- Control over skyrmion stability, shape, and size.

## Abstract

An external off-resonant pumping is proposed as a tool to control the Dzyaloshinskii-Moriya interaction (DMI) in ferromagnetic layers with strong spin-orbit coupling. Combining theoretical analysis with numerical simulations for an $s$-$d$-like model we demonstrate that linearly polarized off-resonant light may help stabilizing novel noncollinear magnetic phases by inducing a strong anisotropy of the DMI. We also investigate how with the application of electromagnetic pumping one can control the stability, shape and size of individual skyrmions to make them suitable for potential applications.
