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. WebMay 1, 1984 · The tetragonal crystallographic structure of this compound Nd 2 Fe 14 B is determined (space group P4 2 /mnm). This structure is related to the hexagonal CaCu 5 -type structure which is the fundamental basis for the crystal structure of many rare earth-transition metal compounds. References (4) M.
