论文摘要
在这封信中，我们报告了锑（SB）晶体中极较大的非饱和线性磁化（MR）的观察。在2K时，在2K时的极大磁磁性（XMR）为43000％，在9T的磁场上观察到室温下的大型不饱和MR $ \ sim \ $ 70％。霍尔测量结果显示出非常高的移动性$ \ sim \ $ 3.8 x 10 $^{4} $ cm $^{2} $/v载载流子和载体浓度和移动性的强度依赖性。 MR和交叉场（B $ _ {C} $）从二次到线性MR的缩放率具有移动性和迁移率倒数，描述了该晶体中大型线性MR的经典起源，如教区和Littlewood（PL）模型（PL）模型。
In this letter we report the observation of extremely large non-saturating linear magnetoresistance (MR) in Antimony(Sb) crystal. An extremely large magnetoresistance (XMR) of 43000% at 2K and large unsaturating MR$\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.
