| Abstract Scope |
The permanent magnets (PM) industry heavily relies on rare earth (RE) elements, whose market is largely dominated and restricted by China. Consequently, there has been a growing interest in the development of RE-lean PMs in recent years. One group of compounds that aims to reduce the reliance on RE elements, compared to the widely used SmCo5 and Nd2Fe14B magnets, is the ThMn12-type structure family. Among these compounds, Nd-based 1:12 alloys exhibit promising properties for permanent magnet applications. However, to meet the requirements of PMs, improvements in magnetocrystalline anisotropy are necessary. This can be achieved through nitrogenation. To develop an optimized nitrogenation process for these alloys, this study examines the evolution of the crystal structure over time during the nitrogenation process, conducted under different applied pressures. Magnetic properties of non-nitride and nitride compounds will be presented. |
