Schematic of magnon-engineered thermal transport in a ferromagnetic metal / magnetic insulator junction (a) and a ferromagnetic metal / non-magnetic insulator junction (b). When magnons can pass through the interface, the thermal conductivity of the ferromagnetic metal increases and the interfacial thermal resistance decreases compared to when they cannot pass through.
