Novel magnets exhibit strong room-temperature stability and improved magnetic coercivity, suggesting advances in magnet technology.
A novel (Sm,Tm) 2 Co 17 -type magnet is developed with an α of −0.008%/°C from 20 to 150 °C, while maintaining a B r of 9.25 kG and a ( BH ) max of 19.26 MGOe, and an optimized high-temperature process further improves H cj by 152% to 25.03 kOe.
