论文摘要
具有非平凡带结构的过渡金属二分法剂具有各种引人入胜的物理特性，并引发了激烈的研究兴趣。在这里，我们对制备的ZRTE2纳米板进行了系统的磁转运测量。我们透露，在存在平行的电场和磁场存在下，在高场区观察到的负纵向磁倍率可能源于纳米板中过量的ZR引起的电导率波动。此外，参数图，平面霍尔电阻率是面内各向异性磁倍率的功能，具有带有偏移的轨道中心的椭圆形图案，从而进一步增强了电导率波动的证据。我们的工作为拓扑材料中的运输现象提供了一些有用的见解。
Transition metal dichalcogenides with nontrivial band structures exhibit various fascinating physical properties and have sparked intensively research interest. Here, we performed systematic magnetotransport measurements on mechanical exfoliation prepared ZrTe2 nanoplates. We revealed that the negative longitudinal magnetoresistivity observed at high field region in the presence of parallel electric and magnetic fields could stem from the conductivity fluctuations due to the excess Zr in the nanoplates. In addition, the parametric plot, the planar Hall resistivity as function of the in-plane anisotropic magnetoresistivity, has an ellipse-shaped pattern with shifted orbital center, which further strengthen the evidence for the conductivity fluctuations. Our work provides some useful insights into transport phenomena in topological materials.
