Title: High Mobility Charge Transport in a Multicarrier Altermagnet CrSb
(Submitted on 28 Mar 2024)
Abstract: A newly identified magnetic phase called altermagnet is being actively studied because of its unprecedented spin-dependent phenomena. Among the candidate materials, CrSb has a particularly high transition temperature and a large spin-splitting energy, but its transport properties have remained unexplored. In this study, we report the magnetotransport properties of CrSb measured on single crystals. We found that the Hall resistivity shows a nonlinear dependence on the magnetic field at low temperatures. From symmetry-based considerations, however, this behavior can not be attributed to an anomalous Hall effect, but to a multicarrier effect. A multicarrier fitting to the in-plane conductivity tensor revealed that there are carriers with high mobilities in CrSb, probably because of the presence of Weyl points in the electronic structure.
