Violation of the magnonic Wiedemann-Franz law in the strong nonlinear regime

Nakata, Koki ; Onuma, Yuichi*; Kim, S. K.*

We show that the ratio of the thermal to spin transport coefficient of magnons in insulating magnets exhibits a different behavior from the linear response and the universal law breaks down in the strong nonlinear regime.
