Controllable manipulation of the transition between many-body ground states or metastable states in charge density wave (CDW) systems by external stimuli such as an electric field or optical pulse is of great interest to distinguish delicate interplay of quantum states and to design functional devices. Here, we report magnetization-induced transport anomalies in magnetic impurity Ni doped NbSe nanowires, which is toward suppressing the anomalous features of pristine CDW states and inducing the typical transport characteristics of disordered metallic phase accompanied by new emergent metastable CDW states or a tunneling-like transport behavior. These transport switching phenomena are ascribed to out-of-equilibrium disorder introduced by the reorientation of local charge/spin-density-wave domains, which partly retain even after switching off the magnetic field. Our observation will promote the understanding of the interaction between the CDW and the magnetic field coupled by magnetic impurities and pave a way to tune the CDW transport by magnetization, which may contribute to the development of CDW-based devices.

Ni 掺杂 NbSe3 纳米线中磁场介导的电荷密度波传输

通过电场或光脉冲等外部刺激对电荷密度波（CDW）系统中多体基态或亚稳态之间的转变进行可控操纵，对于区分量子态的微妙相互作用和设计功能器件非常有意义。在这里，我们报告了磁性杂质 Ni 掺杂 NbSe 纳米线中磁化引起的输运异常，其目的是抑制原始 CDW 态的异常特征，并诱导无序金属相的典型输运特征，并伴随新出现的亚稳态 CDW 态或类隧道效应。运输行为。这些传输切换现象归因于局部电荷/自旋密度波域重新定向而引入的不平衡无序，即使在关闭磁场后，这些无序也部分保留。我们的观察将促进对 CDW 与磁性杂质耦合的磁场之间相互作用的理解，并为通过磁化调节 CDW 传输铺平道路，这可能有助于基于 CDW 的器件的开发。
