Improved magnetic properties and optimized preparation process of (MM)–Fe–B magnets
Substitution of Nd element with misch metal (MM) element in the RE–Fe–B magnets has been set off as an effective method to decrease the cost of RE–Fe–B materials and ensure a more balanced utilization of rare-earth elements. In the present work, the composition of MM x Fe 94 −x B 6 ( x = 14 and 16)...
