In this work, we have predicted a giant thermal magnetoresistance for the thermal photon transport based on the tunable magnetoplasmon of graphene. By applying an external magnetic field, we find that the heat flux can be modulated by approximately three orders of magnitude. Accordingly, both negative and giant relative thermal magnetoresistance ratios are achieved for magnetic fields with a maximum strength of 4 Tesla. This effect is mainly caused by the suppression and enhancement of scattering interactions mediated by a graphene magnetoplasmon. Specifically, it has never been achieved before for nanoparticles, which have no response to magnetic fields. The effect is remarkable at these reasonable strengths of fields and, thus, has considerable significance for real-life applications. It is also expected to enable technological advances for thermal measurement-based magnetic sensors and magnetically thermal management.

石墨烯磁等离子体驱动的巨热磁电阻

在这项工作中，我们基于石墨烯的可调磁等离子体预测了热光子传输的巨大热磁电阻。通过施加外部磁场，我们发现热通量可以调制大约三个数量级。因此，对于最大强度为 4 特斯拉的磁场，实现了负的和巨大的相对热磁阻比。这种效应主要是由石墨烯磁等离子体介导的散射相互作用的抑制和增强引起的。具体来说，对于对磁场没有响应的纳米粒子，以前从未实现过。在这些合理的场强下，效果是显着的，因此对现实生活中的应用具有相当大的意义。
