AbstractThe structure and magnetic properties of Pr16Fe84-xBxNz (x = 0, 2, 4, 6, 8, 10) and PryFe92-yB8Nz = (y = 20, 25, 30) alloys prepared by mechanical alloying using pyrolytic boron nitride (p-BN) as one of starting materials have been investigated. It is found that with increasing the content of p-BN, the magnetic phase transforms from ferromagnetic Pr2Fe17- to Pr2Fe14B-type phase, and finally to paramagnetic Pr1.1Fe4B4-type one. When the Pr2Fe17- and Pr2Fe14-B-type phases coexist, the nitrogen atoms occupy interstitial sites more preferentially in the Pr2Fe14B-type phase than in the Pr2Fe17-type one. Curie temperature of Pr2Fe14BNdelta phase is about 35 K higher than that of Pr2Fe14B phase, which originates from the occupation of nitrogen atoms in the interstitial sites of the Pr2Fe14B lattice. A coercivity as high as 23.5 kOe has been achieved for N-containing Pr-Fe-B alloys with y = 25. (C) 2003 Elsevier B.V. All rights reserved.
