| 英文摘要 | The crystallographic and intrinsic magnetic properties of hydride r3fe29-xtxhy (r=y, ce, nd, sm, gd, tb, and dy; t=v and cr) have been investigated. the lattice constants and the unit cell volume of r3fe29-xtxhy decrease with increasing r atomic number from nd to dy, except for ce, reflecting the lanthanide contraction. regular anisotropic expansions, mainly along the a- and b-axis rather than along the c-axis, are observed for all the compounds upon hydrogenation. hydrogenation leads to an increase in curie temperature. first-order magnetization processes (fomp) occur in magnetic fields of around 1.5 t and 4.0 t at 4.2 k for nd3fe24.5cr4.5h5.0 and tb(3)fc(27.0)cr(2.0)h(2.8), and around 1.4 t at room temperature for gd3fe28.0cr1.0h4.2 abnormal crystallographic and magnetic properties of ce3fe29-xtxhy suggest that the ce ion is non-triply ionized. |
