Recent Advances in Chemical Vapor Deposition of Two‐Dimensional Magnetic Oxides

ABSTRACT 2D magnetic oxides have emerged as a pivotal class of materials due to their exceptional environmental stability and tunable magnetic functionalities. Recent advancements in the synthesis of 2D magnetic oxides have opened unprecedented opportunities for next‐generation technologies, ranging from spintronics to quantum computing. This review provides a comprehensive analysis of synthesis methodologies and magnetic phenomena in these materials. We first classify 2D magnetic oxides based on structural dimensionality (layered/non‐layered) and compositional complexity (binary/ternary systems). Subsequently, we detail advanced vapor‐phase synthesis strategies, encompassing additive‐assisted growth, spatially confined epitaxy, phase/interface engineering, and heteroatom/heterostructure integration. The intrinsic magnetic properties—including room‐temperature ferromagnetism and thickness‐dependent spin ordering—are rigorously validated through multimodal characterization techniques such as vibrating sample magnetometry (VSM), magnetic force microscopy (MFM), magneto‐optic Kerr effect (MOKE), and superconducting quantum interference device (SQUID) measurements. In addition, we discuss the critical challenges associated with wafer‐scale integration and air stability, and propose strategies for designing robust 2D oxide architectures with tailored magnetic responses, providing a roadmap for both fundamental research and device innovation.
