Tunable Magnetism and Transport in Intercalated Layered Magnetic Chalcogen–Halides and Oxyhalides

Van der Waals (vdW) magnets have attracted growing attention for their potential in spintronic and information applications, where high-quality bulk crystals with minimal defects are essential for both fundamental studies and device integration. CrSBr, an air-stable layered orthorhombic antiferromagnet, exhibits A-type magnetic ordering with in-plane ferromagnetism and interlayer antiferromagnetic coupling. Here, we carry out systematic electrochemical intercalation studies on high-quality CrSBr single crystals to probe the evolution of their magnetic and transport behaviors.

To further extend the chemical and structural space of layered magnetic systems, we have also synthesized a large series of orthorhombic magnetic oxyhalide single crystals (e.g., CrOCl, FeOCl, VOCl), which share similar air stability, layered octahedral frameworks and interlayer coupling characteristics with CrSBr. Their structural quality, and emerging magnetic and transport properties will be discussed as part of a comparative framework for understanding tunable magnetism in low-dimensional chalcogen–halide and oxyhalide systems
