This repository contains data from "Magnetism and Neel skyrmion dynamics in GaV4S8-ySey" and the corresponding SI.
It is grouped by Figure and includes the data plotted in the figure, and, where possible, the raw data used to generate it.
Information on each is provided below.

If there are issues with this repository, or to get in touch about the paper, please email tom.lancaster@durham.ac.uk.
