论文摘要
研究了带有不同RRR的拓扑手性半学COSI的两个样品的横向和纵向磁倍率（MR）。结果表明，科勒规则适用于横向MR。在低还原磁场下纵向MR的情况下，Kohler规则也可以实现。纵向MR曲线的急剧偏差，用于低RRR的样品与高场在Kohler预测中的样本揭示了其在较高磁场处发生符号变化的趋势。观察到Shubnikov de haas量子振荡，并在较低温度下的RRR 9.33中的垂直和磁场的垂直和平行构型和平行构型中进行分析。
The transverse and longitudinal magnetoresistance (MR) of two samples of the topological chiral semimetal CoSi with different RRR was studied. It is shown that the Kohler rule works for the transverse MR. The Kohler rule is also fulfilled in the case of longitudinal MR at a low reduced magnetic field. A sharp deviation of longitudinal MR curve for sample with low RRR from the Kohler prediction at high fields reveals its tendency to a sign change at higher magnetic fields. The Shubnikov de Haas quantum oscillations were observed and analyzed in both perpendicular and parallel configurations of the current and magnetic field in sample CoSi 1 with RRR 9.33 at low temperatures.
