自旋量热学是控制磁性纳米结构中的自旋、电荷和热流的科学和技术。旋转自由度为热电发电提供了尚未被充分探索的新策略。在简单介绍了传统的热电学和自旋电子学之后，我们简要回顾了自旋量热电子学的物理学。我们讨论了金属磁体中基于双电流模型的自旋相关热电性，以及铁磁体中基于自旋波激发的自旋Seebeck和Peltier效应。我们推导了几种自旋量热电子器件的效率和优值系数ZT的表达式。
Spin caloritronics is the science and technology to control spin, charge, and heat currents in magnetic nanostructures. The spin degree of freedom provides new strategies for thermoelectric power generation that have not yet been fully explored. After an elementary introduction into conventional thermoelectrics and spintronics, we give a brief review of the physics of spin caloritronics. We discuss spin-dependent thermoelectrics based on the two-current model in metallic magnets as well as the spin Seebeck and Peltier effects that are based on spin wave excitations in ferromagnets. We derive expressions for the efficiency and figure of merit ZT of several spin caloritronic devices.
