Abstract
We report the magnetotransport properties of zirconium pentatelluride (ZrTe5) in the Dirac semimetal phase, focusing on its magnetoresistance behavior at low temperatures. Pronounced Shubnikov–de Haas oscillations were observed in the low magnetic field regime. In the quantum limit, linear magnetoresistance and behavior consistent with a topological phase transition emerge. In-depth analyses of these phenomena and their temperature dependences suggest that both the chemical potential and the Fermi velocity may play an important role in determining the transport properties of ZrTe5 in the quantum limit. Our findings highlight the importance of band parameters in topological transport and provide insights for future studies of topological materials and the design of quantum devices.
