反常能斯特效应(ANE)是研究已久的热磁效应之一，由于人们对自旋热电子学的兴趣日益增加，它再次引起了人们的注意。对于阐明热、自旋和电荷之间的相互作用，以及在高效能量收集设备中的应用，ANE的控制都是一个重要的课题。本文讨论了与ANE的调制有关的各种问题，并讨论了将其应用于热电的可能性。综述了对环氧乙烷材料依赖性的系统研究和环氧乙烷各向异性的发现。还报道了颗粒薄膜中的ANE增强和铁磁性氧化物薄膜中的ANE的电场控制。这篇综述提供了对ANE的调制的物理知识，并提出了几种有效利用ANE在“热”自旋量热场中的方法。
The anomalous Nernst effect (ANE), one of the thermomagnetic effects studied for a long time, is attracting attention again owing to the increased interest in spin caloritronics. Control of the ANE is an essential topic for not only clarifying the interplay among heat, spin, and charge but also application to high-efficiency energy-harvesting devices. In this review, various topics related to the modulation of the ANE are discussed and the possibility of methods for its thermoelectric application are discussed. Systematic studies of the material dependence of the ANE and the discovery of anisotropy in the ANE are reviewed. Enhancement of the ANE in granular thin films and control of the ANE in a ferromagnetic oxide thin film by electric field are also reported. This review provides physical knowledge of the modulation of the ANE and proposes several ways of effectively utilizing the ANE in the “hot” spin caloritronic field.
