Spin Seebeck effect through antiferromagnetic NiO

Physical Review B, 2016
We report temperature-dependent spin-Seebeck measurements on Pt/YIG bilayers and Pt/NiO/YIG trilayers, where YIG (Yttrium iron garnet, Y$_3$Fe$_5$O$_{12}$) is an insulating ferrimagnet and NiO is an antiferromagnet at low temperatures. The thickness of the NiO layer is varied from 0 to 10 nm.

Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

Advanced Electronic Materials, EarlyView.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Effect of Regiochemistry on Doping and Thermoelectric Properties of n‐Doped Fullerene Derivatives

Advanced Electronic Materials, EarlyView.
Three fullerene derivatives doubly substituted with diethylene glycol chains (PDEG‐2) is presented. The different regiochemistry significantly affects the crystallinity and consequently the dielectric properties, electronic transport, and doping efficiency. By striking a balance between compatibility with the molecular dopant N‐DMBI and crystallinity a

Interfacial spin Seebeck effect in noncollinear magnetic systems

Physical Review B, 2019
The interplay between spin and heat currents at magnetic insulator|nonmagnetic metal interfaces has been a subject of much scrutiny because of both fundamental physics and the promise for technological applications. While ferrimagnetic and, more recently, antiferromagnetic systems have been extensively investigated, a theory generalizing the heat-to ...

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
