- Аннотация: The solubility of hydrogen and deuterium in HfRu and ZrRu was measured at 600 K and pressures up to 7 GPa. HfRuH(D) almost-equal-to 3.6 and ZrRuH(D)1.6-2.2 were synthesized. At ambient pressure these were shown to be superconductors with T(c) almost-equal-to 4.5 and 3 K respectively. No difference between the T(c) values of the hydrides and deuterides of the same compound was detected. X-ray diffraction at 100 K has shown the metal sublattices of HfRuH(x)(D(x)) and ZrRuH(x)(D(x)) to be base-centred orthorhombic with very similar unit cell parameters. The crystal structures of HfRuH3.6 and HfRuD3.6 determined by neutron diffraction at 120 K were of the ZrNiH3 type. The observed superconducting and structural properties of HfRuH(x)(D(x)) and ZrRuH(x)(D(x)) agree with the predictions of the rigid d-band model. The applicability of this model to other high pressure hydrides is discussed.
