| 中文摘要 | a systematic study of the structural and intrinsic magnetic properties of the hydrides r3fe29-xcrxhy (r = y, ce, nd, sm, gd, tb, and dy) has been performed. hydrogenation lends to a relative volume expansion of the unit cell and a decrease in x-ray density for each compound. anisotropic expansions mainly along the n- and b-axes rather than along the c-axis for all of the compounds upon hydrogenation are observed. the lattice constants and the unit-cell volume of r3fe29-xcrx and r3fe29-xcrxhy decrease with increasing r atomic number from nd to dy, except for ce, reflecting the lanthanide contraction. hydrogenation results in an increase in the curie temperature and a corresponding increase in the saturation magnetization at room temperature for each compound. after hydrogenation a decrease of 0.34 mu(b)/fe in the average fe atomic magnetic moment and a slight increase in the anisotropy field for y3fe27.2cr1.8 are achieved at 4.2 k. 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 td3fe27.0cr2.0h2.8, and around 1.4 t at room temperature for gd3fe28.0cr1.0h4.2. the abnormal crystallographic and magnetic properties of ce3fe25.0cr4.0 and ce3fe25.0cr4.0h5.4 suggest that the ce ion non-triply ionized. |
