| 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, carbides, and the Sm-3 (Fe,Ti)(29)N-5 compounds, Much of our recent work is focused on the Sm-2(Fe,Ga)(17)C-x alloys where we used melt spinning and subsequent annealing to obtain 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 Th2Zn17-type structure but with a unit-cell expansion Delta VV up to 5% compared to the host materials, The Sm2Fe14-xCoxSi2Cz, carbides maintain the Th2Zn17-type structure when z=1 and transform to the BaCd11-type structure when z = 2, A very large anisotropy field with an applied magnetic field (Ha) value of 227 kOe for Sm2Fe14Si2N2.6 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 Curie temperature (T-c) of 486 and 750 K, respectively, The room temperature saturation magnetization is 119 emu/g for the parent compounds and 145 emu/g 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. |
