本文对自旋密度波（SDW）量级的巡游反铁磁体进行了全面的输运研究。电阻率，热导率，霍尔，塞贝克，能斯特效应表现出明显的异常SDW过渡。在高于我们的数据的温度下，我们的数据为大波动机制提供了强有力的证据，该机制延伸到电阻率、塞贝克效应和能斯特效应。从我们的结果与其他原型SDW材料的比较，即，LaFeAsO和铬，我们得出结论，许多观察到的功能是通用字符。
We present a comprehensive transport investigation of the itinerant antiferromagnetwhich undergoes a spin density wave (SDW) order below. The electrical resistivity, the thermal conductivity, and the Hall, Seebeck, and Nernst effects exhibit pronounced anomalies at the SDW transition. At temperatures higher thanour data provide strong evidence for a large fluctuation regime which extends up toin the resistivity, the Seebeck effect, and the Nernst effect. From the comparison of our results with other prototype SDW materials, viz., LaFeAsO and chromium, we conclude that many of the observed features are of generic character.
