中文摘要	a systematic investigation of crystallographic and intrinsic magnetic properties of the hydrides r3fe29 - xvxhy (r = y, ce, nd, sm, gd, tb, and dy) has been performed in this work. the lattice constants a, b, and c and the unit cell volume of r3fe29 - xvxhy decrease with increasing rare-earth atomic number from nd to dy, except for ce, reflecting the lanthanide contraction. hydrogenation results in regular anisotropic expansions along the a-, b-, and c-axes in this series of hydrides. abnormal crystallographic and magnetic properties of ce3fe27.5v1.5h6.5, like ce3fe27.5v1.5, suggest that the ce ion is non-triply ionized. hydrogenation leads to the increase in both curie temperature for all the compounds and in the saturation magnetization at 4.2 k and rt for r3fe29 - xvx with r = y, ce, nd, sm, gd, and dy, except for tb. hydrogenation also leads to a decrease in the anisotropy field at 4.2 k and rt for r3fe29 - xvx with r = y, ce, nd, gd, tb, and dy, except for sm. the ce3fe27.5v1.5 and gd3fe28.4v0.6 show the larger storage of hydrogen with y = 6.5 and 6.9 in these hydrides.
