Abstract
Hexagonal ferrites are a class of functional magnetic materials with typical hexagonal magnetoplumbite crystal structures. Owing to their strong magnetocrystalline anisotropy, broadband ferromagnetic resonance response, excellent chemical stability, and unique self-biasing potential, they exhibit irreplaceable application value in fields such as microwave communication, electromagnetic protection, and spintronics. This paper systematically expounds the crystal structure characteristics and core magnetic properties of hexagonal ferrites, combs the technical key points and innovation directions of mainstream preparation processes for bulk, thin/thick film, and textured materials, and deeply analyzes their application status and practical effects in microwave non-reciprocal passive devices, electromagnetic interference suppression and absorbing materials, ultra-high-density magnetic storage, and other fields. Aiming at the core challenges faced by current research, such as high-frequency low-loss bottlenecks, insufficient process compatibility, and difficulty in balancing performance and cost, the future breakthrough directions including atomic-level structure regulation, low-temperature compatible preparation, multifunctional heterojunction construction, and green preparation are prospected, which provides comprehensive theoretical reference and practical guidance for the research and development and industrialization of high-performance hexagonal ferrites.关键词
