Mechanochemical synthesis of rare earth 3D transition metal submicron particles with the R2Fe14B structure WebFeb 1, 1986 · For Nd 70 Cu 30-doped magnets, the increment of coercivity is only 1.2 kOe. Meanwhile, Dy 70 Cu 30-doped and (Nd 0.5 Dy 0.5) 70 Cu 30-doped magnets show an almost identical enhancement of coercivity of about 4.4 kOe. Importantly, the latter magnet shows a beneficial effect of reducing the usage of Dy from 1.6 wt% to 0.8 wt%. TEM …
