论文摘要
层次的Zrte $ _5 $似乎表现出几种外来行为，这些行为最近引起了巨大的兴趣，尽管确切的特性仍然高度争议。其中，我们发现了狄拉克/Weyl半金属行为，低温转运显示出非平凡的自旋纹理以及潜在的弱或强拓扑阶段。最近已经阐明了电阻率的异常行为是从电子结构中的带移动来阐明的。我们的工作检查了Zrte $ _5 $样品在多载波传输的背景下，磁通转移行为。结果与AB-Initio频带结构计算结合，表明在大多数温度范围内，Zrte $ _5 $的许多传输特征可以通过源自复杂Fermi表面的半经典多层传输模型来充分说明。
The layered material ZrTe$_5$ appears to exhibit several exotic behaviors which resulted in significant interest recently, although the exact properties are still highly debated. Among these we find a Dirac/Weyl semimetallic behavior, nontrivial spin textures revealed by low temperature transport, and a potential weak or strong topological phase. The anomalous behavior of resistivity has been recently elucidated as originating from band shifting in the electronic structure. Our work examines magnetotransport behavior in ZrTe$_5$ samples in the context of multicarrier transport. The results, in conjunction with ab-initio band structure calculations, indicate that many of the transport features of ZrTe$_5$ across the majority of the temperature range can be adequately explained by the semiclassical multicarrier transport model originating from a complex Fermi surface.
