自旋卡诺电子学研究进展
Recent development of spin caloritronics
-
摘要: 近年来，随着自旋电子学的迅猛发展，人们发现电子自旋流与热流之间存在相互作用，从而产生了一门新兴的领域——自旋卡诺电子学(spin caloritronics)。该学科旨在通过增加电子自旋这一新的自由度来提高热效应的品质因数。文章介绍了自旋卡诺电子学的研究进展，包括自旋相关泽贝克效应、自旋泽贝克效应、磁性隧道结的热电效应以及热自旋转矩；值得关注的是，自旋泽贝克效应给出了一种非常优化的构型来验证自旋热电效应。Abstract: With the fast development of spintronics, the interaction between spin and heat flow attracts considerable interesting. A field known as spin caloritronics emerged, which fo-cuses on increasing the thermoelectric figure of merit by adding“spin”, a new degree of freedom. Here we give an overview of the recent development of spin caloritronics:including spin-depen-dent Seebeck effect, spin Seebeck effect, thermoelectric effect of magnetic tunnel junctions and thermal spin-transfer torques in a quit optimized geometry.
