Recent Progress in Spin Seebeck Effect

Material Sciences, 2014
自旋Seebeck效应是自旋电子学的一个新兴领域，它指的是在特定条件下，在强自旋轨道耦合的非磁金属材料与铁磁绝缘体等材料接触时，界面出现温度梯度诱导产生的自旋流注入现象。它实现了从热流到自旋流的转换，同时这种自旋流注入可以通过非磁金属中的逆自旋霍尔效应转化为电荷电压。我们将介绍这个领域最近的实验进展，综述了自旋Seebeck效应的最新机制理论，最后作了器件应用方面的介绍，并对相关理论和实验研究进行了展望，指出要应用于未来热电转换仍是一个挑战性的任务并提出一些解决思路。Spin Seebeck effect, as an emerging field of spintronics, refers to the phenomenon that under spe-cific conditions, on

Spin Seebeck effect of interacting spinons

Physical Review B
We present the theory of the longitudinal spin Seebeck effect between a Heisenberg spin-1/2 chain and a conductor. The effect consists of the generation of a spin current across the spin chain-conductor interface in response to the temperature difference between the two systems.

Magnetic field control of the spin Seebeck effect

, 2015
The origin of the suppression of the longitudinal spin Seebeck effect by applied magnetic fields is studied. We perform numerical simulations of the stochastic Landau-Lifshitz-Gilbert equation of motion for an atomistic spin model and calculate the ...

Thermal creation of a spin current by Seebeck spin tunneling

, 2013
International audienceThe thermoelectric analog of spin-polarized tunneling, namely Seebeck spin tunneling, is a recently discovered phenomenon that arises from the spin-dependent Seebeck coefficient of a magnetic tunnel contact.

Abnormal spin Seebeck effect near compensation temperature in Tb3Fe5O12 garnet films

npj Spintronics
We report the abnormal spin Seebeck effect (SSE) observed in Tb3Fe5O12(TbIG)/Pt heterostructures near the compensation temperature (T comp) of TbIG. As the temperature approaches T comp from room temperature, a rapid decline is shown in the spin Seebeck ...

Thickness dependence on dynamical spin injection driven by thermal effects in CoFeB/Pt bilayer

Scientific Reports
In ferromagnetic metal (FM)/non-magnetic metal (NM) bilayer structures, dynamical spin injection is primarily attributed to spin pumping at the interface.
