Scientists propose a new spin caloritronics concept called “spintronic thermal management” and provide a comprehensive overview of basic principles, physical behaviors, and heat control functionalities associated with the concept.
The spin-Seebeck effect (SSE) in linearly hydrogenated carbon nanotubes (CNTs) is realized, where partial hydrogenation makes CNTs acquire magnetism. Moreover, an odd–even effect of the SSE is observed, and the even cases could be used as spin-Seebeck diodes, without the need for an electric field or gate voltage.
This chapter focuses on spin caloritronics, the field combining thermoelectrics with spintronics and nanomagnetism. Spin caloritronics is concerned with new physics related to spin, charge, and entropy/energy transport in materials and nanoscale structures and devices. Heat and spin effects are also coupled by the dissipation and noise associated with magnetization dynamics. Spin caloritronics lead to low power nan-scale devices and provide new strategies for waste heat recovery.
