Record (BH)max of 36.5 MGOe for the La-Nd based magnet

CMI researchers at Ames National Laboratory conducted the research for this highlight

line graph shows HD and ribbon samples sintered, heat treated, and diffusion treated using the same procedure. HD sample used the PrCuAl powder that was hydrogen decrepitated before ball milling, while the ribbon sample used the normal PrCuAl powders. The HD treated PrCuAl powder helps the grains to be better aligned.
