Magnons are quanta of spin-wave excitations and are likely to play a major role in the physical mechanisms of combining spin and heat transport. Now, a new device that enables the properties of magnons to be measured independently of the thermoelectric contribution of electrons and phonons is shown, providing crucial information for understanding the physics of electron–magnon interactions, magnon dynamics and thermal spin transport.
