论文摘要
我们报告了低于$ 30 $ MT的单晶和政治晶体的$ 30 $ MT的出现类似铁磁性的异常大厅效应（AHE）。在磁化测量中未佐证运输中铁磁性的特征，因此表明在需要次的表面和晶粒边界处诱导了非脑磁性的诱导。随着磁场和温度的增加，AHE的抑制与先前关于BI超导性的报道相吻合，这表明两种现象之间存在相互作用。
We report the occurrence of ferromagnetic-like anomalous Hall effect (AHE) below $30$ mT in bismuth single and policrystals. The signatures of ferromagnetism in transport are not corroborated in magnetization measurements, thus suggesting the induction of non-intrinsic magnetism at surfaces and grain boundaries in bismuth. The suppression of the AHE with the increase of magnetic field and temperature coincides with previous reports of superconductivity in Bi, suggesting an interplay between the two phenomena.
