研究了氢对Dy_2Fe_（17）H_x单晶结构和磁性的影响。主体合金的对称性在氢化后得以保留。结果表明，磁特性（居里温度和磁晶各向异性）对氢的存在高度敏感，并随着氢含量的变化而发生显著变化。结果进行了讨论的模型考虑的四极和4f电子磁矩的稀土离子与间隙氢原子的相互作用。
The effect of hydrogen on structural and magnetic properties of the Dy2Fe17Hxsingle crystal was investigated. The host alloys symmetry is retained upon hydrogenation. It was found that the magnetic characteristics (such as the Curie temperature and magnetocrystalline anisotropy) are highly sensitive to the presence of hydrogen and exhibit dramatic changes with changing of H content. The results are discussed in terms of a model considering the interaction of the quadrupole and 4f electron magnetic moments of the rare-earth ion with the interstitial hydrogen atoms.
