论文摘要
我们通过实验研究手性PT/CO/RU多层中各个天际的热电学特征。使用受控成核，单个天际歼灭和磁场依赖性测量的组合，表征了单个天空的热电特征。观察到的特征是通过天空旋转结构的异常Nern的效应来解释的。讨论了对观察到的热电学特征的拓扑贡献。这种热电学表征允许对天空的非侵入性检测和计数，并可以对拓扑量表对拓扑热效应进行基本研究
We experimentally study the thermoelectrical signature of individual skyrmions in chiral Pt/Co/Ru multilayers. Using a combination of controlled nucleation, single skyrmion annihilation, and magnetic field dependent measurements the thermoelectric signature of individual skyrmions is characterized. The observed signature is explained by the anomalous Nernst effect of the skyrmions spin structure. Possible topological contributions to the observed thermoelectrical signature are discussed. Such thermoelectrical characterization allows for non-invasive detection and counting of skyrmions and enables fundamental studies of topological thermoelectric effects on the nano scale
