Abstract

The magnetic degree of freedom or magnetism-driven mechanisms have emerged as a promising lever for optimizing thermoelectric performance. These mechanisms introduce new physical principles beyond traditional band engineering strategies. This review presents a systematic overview of recent advances in magnetically enhanced thermoelectric effects, highlighting both longitudinal and transverse transport regimes. In the longitudinal case, multiple magnetic mechanisms have been identified, including spin entropy, spin fluctuations, magnon and paramagnon drag, superparamagnetic dynamics, and magnetic-field-induced modulation of the Seebeck coefficient. Each of these mechanisms modifies carrier transport through distinct spin-related or field-activated processes. In the transverse regime, linear band dispersion and Berry curvature give rise to strong Nernst and anomalous Nernst responses under external magnetic fields and magnetic ordering state. These effects demonstrate the key role of magnetic degrees of freedom in enhancing thermoelectric performance. The corresponding mechanisms and representative material systems discussed herein offer valuable insights for the future optimization of thermoelectric materials through magnetic degrees of freedom.

纵向和横向热电中的磁策略

磁性自由度或磁性驱动机制已成为优化热电性能的有前途的杠杆。这些机制引入了超越传统波段工程策略的新物理原理。本文综述了磁增强热电效应的最新进展，重点介绍了纵向和横向输运机制。在纵向情况下，已经确定了多种磁机制，包括自旋熵、自旋涨落、磁振子和顺磁子阻力、超顺磁动力学以及磁场诱导的塞贝克系数调制。这些机制中的每一种都通过不同的自旋相关或场激活过程来改变载流子的输运。在外磁场和磁有序态下，线性频带色散和Berry曲率引起了强能带和反常能带响应。这些效应证明了磁性自由度在提高热电性能方面的关键作用。本文讨论了相应的机理和代表性材料体系，为未来通过磁自由度优化热电材料提供了有价值的见解。
