Anomalous Hall Effect in Bismuth

We report the occurrence of ferromagnetic-like anomalous Hall effect (AHE) below 30 mT in bismuth crystals. 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.
