This dataset supports the manuscipt Brandao J., Azzawi S., Hindmarch A.T., and Atkinson D., 'Understanding the role of damping and Dzyaloshinskii-Moriya interaction on domain wall dynamic behaviour in platinum-ferromagnet nanowires'.

A description of the data and file formats is included below.
Please contact Aidan Hindmarch <a.t.hindmarch@durham.ac.uk> with any questions.


Hysteresis loops are measured on microfabricated wires using focussed magneto-optical Kerr effect magnetometry. Gilbert damping is measured using time-resolved magneto-optical Kerr effect.
Micromagnetic simulations are performed using the Mumax3 code with simulation parameters as described in the citing manuscript text.

All files are TAB delimited ascii and the header contains the quantity and units for each column containing the data shown in the figure. Fits and trendlines shown in the figures are not included. Images and micromagnetic simulation snapshots are also not included, but can be reproduced by running simulations as described.
