  ErCo3-氢化物和TmCo3-氢化物的磁化研究

  摘要：

  摘要 ErCo 3 和TmCo 3 化合物是亚铁磁性的，居里温度分别为401 K和370 K。它们吸收氢以形成 ErCo 3 H 4.3 和 TmCo 3 H 3.3 。从对这些以及其他 RCo 3 氢化物在 4.2 到 300 K 温度区间内的磁化研究，推断氢吸收导致钴的磁矩降低和 R-Co 相互作用减弱（R = 稀土）。除了 GdCo 3 -氢化物的情况外，在高达 21 kOe 的外加场中，在 4.2 K 时未达到磁化饱和。这暗示了扇形稀土时刻的可能性。早先用 R = Gd、Dy 和 Ho 研究的 RCo 3 -氢化物以及 ErCo 3 -氢化物和 TmCo 3 -氢化物在室温下似乎都是磁性有序的。

  High-field magnetization measurements have been carried out for single-crystal gamma-phase hydrides RCo3H(approximately 4) with R = Th and Dy and for powder samples with R = Nd and Gd. The results indicate that these gamma-phase hydrides with R = Y, Ho and Er become antiferromagnetic except for R = Gd at low temperatures due to the appearance of a negative Co-Co intersublattice interaction. A metamagnetic transition of the Co-sublattice magnetization occurs from the antiferromagnetic to the forced ferromagnetic state if the field is applied along the c-axis. GdCo3H(approximately 4), being ferrimagnetic at low temperatures, becomes antiferromagnetic above 32 K. The significant weakening of the R-Co interaction due to hydrogenation leads to a Neel temperature of about 200 K in all hydrides and an almost independent behaviour of the R and Co sublattices in the compounds with R = Nd, Ho and Er. The role of the R-Co interaction in the magnetic behaviour of the hydrides is discussed.

  gamma-phase RCo(3)D(-4) deuterides with R=Y and Er were studied by neutron diffraction analysis at room temperature in the paramagnetic state. Deuterium atoms are distributed over three types of interstitial site 18h(2), 36i(1) and 36i(2) with occupancies of about 90%, 35% and 10% respectively. The deuterium site occupation is compared with that for beta-phase RCo(3) hydrides and with RCo(2) and RCo(5) structures from which the RCo(3) lattice can be constructed.
