Replication Data for the article "Spin-Seebeck Signatures of Spin Chirality in Kagome Antiferromagnets" submitted in Physical Review B (2025).

The file ‘Fig2.txt’ contains the energy of the three spin-wave bands of the kagome antiferromagnet when it is in the (+)- and (-)-chiral state as a function of the momentum along the x- and y-directions, which is plotted in Figure 2 in the paper.

The file ‘Fig3b.txt’ contains the z-component of the spin current in the (+) chiral state, the z-component of the spin current in the (-)-chiral state, as well as the y-component of the spin current in the (+)-chiral state, normalized by the constant y-component of the spin current in the (-)-chiral state, as a function of the applied magnetic field in the z-direction. The data is plotted in Figure 3b in the paper.
