Extremely large linear magnetoresistance in Antimony crystal

In this letter we report the observation of extremely large non-saturating linear magnetoresistance (MR) in Antimony(Sb) crystal. An extremely large magnetoresistance (XMR) of 43000% at 2K and large unsaturating MR$\sim\ $70% at room temperature is observed at the magnetic field of 9T. Hall measurements reveal a very high mobility $\sim\ $3.8 x 10$^{4}$ cm$^{2}$/Vs of charge carriers and strong temperature dependence of carrier concentration and mobility. The respective scaling of MR and crossover field (B$_{c}$) from quadratic to linear MR with mobility and inverse of mobility describes the classical origin of large linear MR in this crystal as suggested by Parish and Littlewood (PL) model for disordered systems.
