| 中文摘要 | In this article, we review our recent studies on new rare-earth intermetallic compounds including the Ga, Si substituted 2:17-type compounds, their nitrides and carbides, and the Sm-3(Fe,Ti)(29)N-5 compounds. Much of our recent work has been focused predominantly in the Sm-2(Fe,Ga)(17)C-x alloys, where we used melt-spinning and subsequent annealing to obtain a high coercivity. The highest coercivity obtained so far was in Sm2Fe14Ga3C2.5, with a value of 12.8 kOe at room temperature. The off-stoichiometric Sm2Fe14-xCoxSi2Ny nitrides maintain the ThZZn17-type structure but with a unit-cell expansion Delta V/V up to 5% compared to the host materials. The Sm2Fe14-xCoxSi2C2 carbides maintain the Th2Zn17-type structure when z=1 and transform to BaCd11-type structure when z=2. A very large anisotropy field with H-a value of 227 kOe for Sm2Fe14Si2N26 and 276 kOe for Sm2Fe10Co4Si2N2.3, is observed at low temperature (1.5 K). The Sm-3(Fe,Ti)(29)N-5 compound and its nitrides show very interesting magnetic properties. Both of these compounds exhibit ferromagnetic ordering with T-c of 486 and 750 K, respectively. The room-temperature saturation magnetization is 119 e.m.u. g(-1) for the parent compounds and 145 e.m.u. g(-1) for the nitrides. The easy-magnetization direction changes from planar to uniaxial upon nitrogenation. The anisotropy field for the nitrides is 12 T at room temperature and 25 T at 4.2 K. |
