Calculated magnon dispersion of yttrium iron garnet

The data is discussed in the associated manuscript, which can be found here:https://arxiv.org/abs/2507.11374In essence, we perform first principles calculations (using density functional theory) to obtain the exchange constants and magnon dispersion of yttrium iron garnet.
