Extremely large and significantly anisotropic magnetoresistance in ZrSiS single crystals

摘要

Recently, the extremely large magnetoresistance (MR) observed in transition metal telluride, like WTe_2, attracted much attention because of the potential applications in magnetic sensor. Here, we report the observation of extremely large magnetoresistance as 3.0 × 10~4% measured at 2K and 9 T magnetic field aligned along [001]-ZrSiS. The significant magnetoresistance change (～1.4 × 10~4%) can be obtained when the magnetic field is titled from [001] to [011]-ZrSiS. These abnormal magnetoresistance behaviors in ZrSiS can be understood by electron-hole compensation and the open orbital of Fermi surface. Because of these superior MR properties, ZrSiS may be used in the magnetic sensors.
