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

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.
