Outline of Research at the Start |
SmFe12-based compounds are potential candidate for the next generation high-performance rare-earth lean permanent magnets. This is due to their superior intrinsic magnetic properties than those of Nd2Fe14B at the elevated temperatures. However, the main challenge toward their industrial application is how to transfer their intrinsic magnetic properties to the extrinsic ones, large coercivity and remanence. In this project, we will overcome this problem by employing a new data-driven research approach to develop anisotropic SmFe12-based sintered magnets with Mr>1.2 T and Hc>2.0 T.
