摘要：

The Curie temperature of Y2Fe17Cx increases linearly with carbon content in the hexagonal phase, 0 ≤ × ≤ 1. It saturates at 520 K for x ≥ 1.1, where the phase becomes rhombohedral. The iron moment and magnetization for Y2Fe17C at T = 0 K and 290 K respectively are 2.08 microB and 1.56 T, 1.65 microB and 1.25 T. Thermopiezic analysis shows that the carbide absorbs hydrogen at 250 °C at 1 bar. Hydrogenated carbides show a further increase in Tc. © 1990.
