| 中文摘要 | The novel ternary rare-earth iron-rich interstitial compounds R-3(Fe,Cr)(29)X-y (R=Nd, Sm and X=N, C) with the monoclinic Nd-3(Fe,Ti)(29) structure have been successfully synthesized. Introduction of the interstitial nitrogen and carbon atoms led to a relative volume expansion Delta V/V of about 6% and an enhancement of Curie temperatures T-c about 268 K for the nitride and about 139 K for the carbide, respectively. The Nd3Fe24.5Cr4.5Xy compounds have a planar anisotropy at room temperature. A first-order magnetization process (FOMP) with critical field B-cr=4.4 T and 3.1 T at room temperature were observed for the Nd-nitride and carbide compounds, respectively. The Sm3Fe24Cr5Xy compounds were found to have a large uniaxial anisotropy of about 18 T at 4.2 K and about 11 T at 293 K. A FOMP with B-cr=2.3 T was also observed in the Sm-nitride compounds at 4.2 K. Magnets with coercivity of mu(oj)H(c) similar to 0.8 T at 293 K has been successfully developed from the Sm3Fe24Cr5Xy (X=N and C) phases. (C) 1997 Elsevier Science S.A. |
