## Description

- description: All-solid-state nanoscale devices capable of efficiently controlling
    a heat flow are crucial for advanced thermal management technologies. Here we
    predict a magnon-driven magnetothermal resistance (mMTR) effect in multilayers
    of ferromagnets and normal metals, i.e. a thermal resistance that varies when
    switching between parallel and antiparallel magnetization orientations of the
    ferromagnetic layers, even in the absence of conduction electrons in the ferromagnets.
    The mMTR arises from an interfacial temperature drop caused by magnon spin accumulations
    and can be engineered by the layer thicknesses, spin diffusion lengths, and spin
    conductances. The mMTR predicted here enables magnetothermal switching in insulator-based
    systems; we already predict large mMTR ratios up to 40% for superlattices of the
    electrically insulating magnet yttrium iron garnet and elemental metals.
