Abstract

As an emerging low-symmetry two-dimensional (2D) magnetic material, CrOCl provides a unique platform for multidimensional physical effect modulation owing to its orthogonal lattice-induced structural symmetry breaking. This review systematically examines the intrinsic properties of CrOCl in magnetic, optical, and thermal domains, revealing its magnetic-field-dependent resistance switching behavior, significant optical anisotropy, and anomalous thermal transport mechanisms. Furthermore, it elaborates on various property modulation strategies, including strain engineering to enhance magnetic ordering temperature, high-pressure-induced phase transitions, dimensional engineering for topological state construction, and carrier doping to surpass room-temperature ferromagnetism limitations. Regarding heterostructure fabrication, the interfacial synergistic effects between CrOCl and materials such as metals and graphene are comprehensively analyzed, elucidating their critical roles in spin valves, quantum transport, and photodetection. With advancements in synthesis techniques like chemical vapor transport, the application prospects of CrOCl-based devices in polarized optical modulation, spin storage, and three-dimensional integrated logic circuits are prospectively explored. By establishing a comprehensive “structural characteristics-property modulation-interface design-functional expansion” framework, this review provides theoretical guidance and technical support for quantum device development in 2D magnetic materials.

二维CrOCl的结构对称性破缺实现了多物理场耦合和功能可调性

CrOCl作为一种新兴的低对称性二维磁性材料，由于其正交晶格诱导的结构对称性破缺，为多维物理效应调制提供了独特的平台。本文系统地研究了CrOCl在磁、光和热领域的固有性质，揭示了其磁场依赖的电阻开关行为、显著的光学各向异性和异常的热输运机制。此外，它详细阐述了各种性质调制策略，包括应变工程以提高磁有序温度，高压诱导相变，拓扑状态构建的尺寸工程，以及超越室温铁磁性限制的载流子掺杂。在异质结构制造方面，全面分析了CrOCl与金属和石墨烯等材料之间的界面协同效应，阐明了它们在自旋阀、量子输运和光探测中的关键作用。随着化学气相输运等合成技术的进步，对crocl器件在偏振光调制、自旋存储、三维集成逻辑电路等方面的应用前景进行了展望。通过建立“结构特性-性能调制-接口设计-功能扩展”的综合框架，为二维磁性材料量子器件的发展提供理论指导和技术支持。
