  Hydrogen site occupation inYPd3withL12structure

  摘要：

  Hydrogen site occupation in a binary metal compound of YPd3 with L1(2) structure is studied experimentally and theoretically. In contradiction to the semiempirical heat of the formation model, which predicts the interstitial site preferably occupied by hydrogen atoms in intermetallic compounds, the present neutron-diffraction study reveals that the hydrogen atoms occupy preferentially the characteristic interstitial site surrounded by six Pd atoms rather than the interstices surrounded by two Y and four Pd atoms. This result is confirmed by the first-principles calculations based on the local-density-functional theory. The difference in the electronic interactions between hydrogen and host atoms is shown to be largely responsible for the occupation of the specified interstitial sties by hydrogen in intermetallic hydride.

  YRu2, YPt2, YPd3 and ScAl2 containing small amounts of Pr as well as on Sc0.95Pr0.05 are reported in order to look for the Kondo behaviour of Pr ions. The logarithmic variation in rho , however, is not apparent in the temperature range of investigation in any of the alloys, although these alloys are potential candidates for exhibiting Kondo behaviour.

  The intrinsic magnetic susceptibilities of the Kondo alloys Y1-xUxPd3 and UCu5-xPdx have been determined from analysis of magnetization isotherms and magnetization versus temperature curves at two magnetic fields. The isotherms indicate the presence of paramagnetic impurities, the magnetization of which was subtracted from measured magnetization data using a scaling relation but without assuming any particular temperature dependence for either the impurity or intrinsic magnetization.

  We present measurements of the thermoelectric power S(T) from 2-300 K in the material Y1-xUxPd3, with x = 0, 0.05, 0.1, 0.2, 0.3, and 0.4. The general behavior for x = 0.05, 0.1 is reminiscent of Kondo materials, characterized by a ''giant,'' positive contribution that is linear in T at low temperatures, and is independent of x. This suggests that the Kondo scale is also independent of x, in contrast to the results of other measurements. The high-temperature thermopower changes from positive to negative as x is varied from 0.1 to 0.3, suggestive of a crossover or transition in electronic structure near x = 0.2. The spin-glass transition of the x = 0.3,0.4 alloys is signaled by a zero crossing of S, similar to that observed for conventional spin glasses.
• The Y–Cu–Pd ternary system at 600°C (0–25 at.% Y): a reinvestigation

  The phase equilibria at 600 degrees C of the ternary system Y-Cu-Pd in the range 0-25 at.% Y have been investigated by means of X-ray powder diffraction and microscopic analyses, Three ternary compounds were found to occur: YCu1.20Pd1.80, YCu2-1.75Pd1-1.25 and YCu3.77Pd1.23. The crystal structure was determined for two compounds: YCu1.20Pd1.80 has the TiNi3 structure type, sp. gr. P6(3)/mmc, a=5.732(1), c=9.383(2) Angstrom, YCu3.77Pd1.23 has the AuBe5 str. type, sp. gr. F (4) over bar 3m, a=7.078(2) Angstrom. The Cu and Pd atoms randomly occupy crystallographic sites in both structures. The electrical resistivity of the ternary compounds is of the metal type and obeys the Bloch-Gruneisen function within the temperature range 4.2-300 K. None of the ternary compounds of the system superconduct above 4.2 K. The traces of superconductivity observed in some alloys are suggested to arise from an unresolved quaternary compound.

• Low-temperature magnetic susceptibility and resistivity measurements and electron probe microanalysis of Y1−xUxPd3

  We have extended the low-temperature magnetic susceptibility and resistivity measurements of Y1-xUxPd3 (x approximate to 0.2) down to millikelvin temperatures. One sample showed Curie-Weiss-like paramagnetic susceptibility between 50 mK and 2 K. Another small sample appeared to have nearly constant susceptibility between 400 mu K and 120 mK. The signal arising from paramagnetic impurities has been estimated from the susceptibility of undoped YPd3 measured between 600 mu K and 170 mK. No signature of superconductivity was observed in the resistivity measurements down to 5 mK. Electron probe microanalysis showed that the sample composition was modulated on a scale of tens of micrometers.
