Description
Summary:Permanent-magnet materials are critical components for green energy technologies, but the intrinsic trade-off between saturation magnetization and coercivity limits their achievable energy density. Here, a new concept of ordered structures is proposed to develop high-performance permanent magnets. This strategy enables a rare combination of high magnetization and high coercivity by introducing new magnetization reversal mechanisms associated with ordered structures. Implications and challenges of building ordered structures for strong magnets are discussed. This Perspective aims to draw the attention of materials research community to the emerging ordered magnets and to motivate active investigations on this topic for creating transformative magnets.
