了解磁性和微观结构之间的微妙联系对于开发更高性能的磁体至关重要。在R-Fe-B（R =稀土）基材料的情况下，这一知识将用于开发与清洁能源技术相关的高矫顽力、无Dy永磁体。结合高分辨率表征、分子动力学和微磁学模拟以及模型厚膜系统，我们对R-Fe-B磁体的矫顽力机制有了新的认识。(C)2012 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Understanding the subtle link between coercivity and microstructure is essential for the development of higher performance magnets. In the case of R-Fe-B (R = rare earth) based materials this knowledge will be used to enable the development of high coercivity, Dy-free permanent magnets, which are relevant for clean energy technologies. A combination of high resolution characterization, molecular dynamics and micromagnetic simulations and model thick film systems has been used to gain valuable new insights into the coercivity mechanisms in R-Fe-B magnets.
