The electrochemical intercalation is one of most powerful tools for tuning the intrinsic properties of quasi-two-dimensional (2D) materials. In this work, ionic organic cations, [Formula: see text] and [Formula: see text], are successfully intercalated into [Formula: see text] interlayer via electrochemical intercalation. The both [Formula: see text] and [Formula: see text] intercalated [Formula: see text] samples show ferrimagnetic transition with the transition temperature of 65 K and 85 K, respectively. Raman spectroscopy, X-ray photoelectron spectroscopy and Hall measurements reveal that the electron doping and sulfur vacancies created by the cation intercalation play important role in the ferrimagnetic transition. Our work provides a new pathway to manipulation of magnetism in layered 2D materials.
电化学插层是调节准二维（2D）材料本征特性的最强大工具之一。在这项工作中，离子有机阳离子[化学式：见原文]和[化学式：见原文]通过电化学插层成功插入到[化学式：见原文]的层间。两种插入了[化学式：见原文]的样品均显示出亚铁磁转变，转变温度分别为65K和85K。拉曼光谱、X射线光电子能谱和霍尔测量表明，阳离子插层产生的电子掺杂和硫空位在亚铁磁转变中起重要作用。我们的工作为调控层状二维材料的磁性提供了一条新途径。
