Giant linear magneto-resistance in nonmagnetic PtBi2

We synthesized nonmagnetic PtBi2 single crystals and observed a giant linear magneto-resistance (MR) up to 684% under a magnetic field μ 0 H  = 15 T at T = 2 K. The linear MR decreases with increasing temperature, but it is still as large as 61% under μ 0 H of 15 T at room temperature. Such a giant...

description We synthesized nonmagnetic PtBi2 single crystals and observed a giant linear magneto-resistance (MR) up to 684% under a magnetic field μ 0 H  = 15 T at T = 2 K. The linear MR decreases with increasing temperature, but it is still as large as 61% under μ 0 H of 15 T at room temperature. Such a giant linear MR is unlikely to be described by the quantum model as the quantum condition is not satisfied. Instead, we found that the slope of MR scales with the Hall mobility, and it can be well explained by a classical disorder model.
