摘要：
在这项工作中，基于石墨烯可调谐磁等离激元，我们预测了热光子传输的巨大热磁阻。通过施加外部磁场，我们发现热流可以被调制约三个数量级。相应地，对于最大强度为4特斯拉的磁场，负相对热磁阻比和巨大相对热磁阻比均得以实现。该效应主要由石墨烯磁等离激元介导的散射相互作用的抑制和增强引起。具体而言，这对于对磁场无响应的纳米颗粒而言是前所未有的。该效应在这些合理的场强下十分显著，因此对现实应用具有重要意义。它还有望推动基于热测量的磁场传感器和磁性热管理的技术进步。
英文摘要：
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, negative and giant relative thermal magnetoresistance ratios are both 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 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 the real-life applications. It is also expected to enable technological advances for the thermal measurement-based magnetic sensor and magnetically thermal management.
