论文摘要
磁性半学的发现最近引起了拓扑和热电学领域的极大关注。在基于Nernst几何形状的热电设备中，需要外部磁铁作为整体零件。我们报告了新发现的硬磁性kagome-lattice Weyl-Semimetal CO3SN2S2SN中的零场Nernst效应。在这种磁性的Weyl-Semimetal中，在80 K时在80 K处的3微伏/K的最大NERNST热电池。我们的结果表明，基于NernST效应，拓扑硬磁半学在低功率热电设备中应用的可能性可能是对这类材料中对运输特性的全面理解有价值的。
The discovery of magnetic topological semimetals recently attracted significant attention in the field of topology and thermoelectrics. In a thermoelectric device based on the Nernst geometry, an external magnet is required as an integral part. We report a zero-field Nernst effect in a newly discovered hard-ferromagnetic kagome-lattice Weyl-semimetal Co3Sn2S2. A maximum Nernst thermopower of 3 microvolt/K at 80 K in zero field is achieved in this magnetic Weyl-semimetal. Our results demonstrate the possibility of application of topological hard magnetic semimetals for low-power thermoelectric devices based on the Nernst effect and are thus valuable for the comprehensive understanding of transport properties in this class of materials.
