Abstract

Quantum thermal transport in magnetic nanomaterials has become a key interdisciplinary topic linking condensed matter physics, spintronics, and energy science. The interplay among spin, lattice, and charge degrees of freedom gives rise to novel heat transport mechanisms that offer new strategies for nanoscale thermal management and energy conversion. This review summarizes recent developments in theoretical modeling and numerical simulations towards quantum thermal transport in magnetic systems, with a focus on main approaches such as nonequilibrium Green’s function, Boltzmann transport equations, and spin lattice dynamics, as well as their variants. Furthermore, the potential applications and existing issues of magnetic nanomaterials are discussed in the context of spin thermoelectric devices, thermal management and regulation, and information control and logic devices. Finally, the review points to the existing challenges in theoretical modeling and numerical simulations for realistic materials and devices, with several potential topics for future efforts.
