High performance MM–FeCo–B spark plasma sintered magnets with nonmagnetic grain-boundary phase

This work presents results on the effect of mischmetal (MM) content on the magnetic properties, phase formation, microstructure, and intergranular interactions in MM12+xFe78-xCo2B6 (x = 0, 4, 8) magnets. The MM-FeCo-B magnets have been prepared by Spark Plasma Sintering method from powders obtained...
