本项目以将热电效应与自旋电子学相结合,计划开展如何利用自旋和磁有序这一自由度来提高余热利用 效率.提出以金属-磁性绝缘体界面为研究主体。计算对自旋赛贝克效应和自旋霍尔磁电阻至关重要的自旋混合电导,针对近期实验上发现的自旋混合电导随温度的变化,开展界面自旋波激发对自旋混合电导的影响的理论研究,进一步发展反铁磁自旋泵浦理论,并与第一原理计算结合,寻找设计具有较大自旋-热耦合的纳米结构.

We plan to combine the development of thermo-electric effect and spintronics, study how to recycler waste heat with the freedom of spin and magnetization. We propose to calculate the electronic structure of metal-insulator interface and the spin mixing conductance of such structure. While spin mixing conductance is curial for the spin Seebeck effect and spin Hall magnetcoresistance of metal-magnetic insulator system. We will look at the sign change of the spin mixing conductance of such system with changing of temperature. We will also develop the formulism to study the spin pumping in antiferromagnetic system and combine it with first principles calculation package. We will searh for the nanostructure with large spin and heat coupling.
