论文摘要
我们介绍了Skyrmion晶格的第一个室温热电签名。这是在Fe3SN2中观察到的，Fe3SN2是一种具有高温天空阶段的巨大dirac fermions的Kagome Dirac晶体。室温天空晶格显示波形的磁场依赖性，而热电器则由电子扩散机制主导，从而可以进行天空气泡晶格检测。我们的结果为基于热梯度的操纵而为未来的基于Skyrmion的设备铺平了道路。
We present first room-temperature thermoelectric signature of the skyrmion lattice. This was observed in Fe3Sn2, a Kagome Dirac crystal with massive Dirac fermions that features high-temperature skyrmion phase. The room-temperature skyrmion lattice shows magnetic-field dependence of the wavevector whereas thermopower is dominated by the electronic diffusion mechanism, allowing for the skyrmionic bubble lattice detection. Our results pave the way for the future skyrmion-based devices based on the manipulation of the thermal gradient.
