Abstract
The structure and magnetic properties of Nd16Fe84-xBxNy alloys prepared by mechanical alloying using pyrolytic boron nitride (p-BN) as starting materi al have been investigated. By increasing the content of boron and nitrogen, the magnetic main phase changes from Nd2Fe17 to Nd2Fe14BNdelta, and finall y transforms into the paramagnetic Nd1.1Fe4B4 phase. The nitrogen and boron contents determine the component of phases and magnetic properties. The en hancement of the Curie temperature of the Nd2Fe14BNdelta phase originates f rom the increase of the interstitial nitrogen content in the Nd2Fe14B latti ce. (C) 2000 Elsevier Science S.A.
