WebApr 29, 2024 · It can be seen that the intrinsic coercivity first increases with Zr substitution, from 62 kA·m −1 (Zr-free) up to highest value of 945 kA·m −1 with 2 at% Zr, and then decreases with further addition of Zr. This indicates that a certain amount of Zr addition favors the coercivity of Pr 9.5 Fe 84 B 6.4 P 0.1 alloy. WebO. Koylu-Alkan, J. M. Barandiaran, D. Salazar, G. C. Hadjipanayis; Affiliations O.
