This lecture covers the fabrication and microstructure of hard magnetic materials, emphasizing the strategies for achieving high coercivity and remanence. It discusses the importance of polycrystalline materials over single crystals, the role of domain wall pinning, and the significance of rare earth elements in creating high-performance magnets. The presentation also delves into the production volume and critical elements of permanent magnets, highlighting their applications in various technologies, including wind energy. Additionally, it explores the saturation magnetization and coercivity of different magnetic materials, providing insights into their properties and applications.
