“…The value of E}irt(pd) was obtained from the E vs k curve of Au so that the corresponding Fermi wave vectors along the specific axes coincide with the Fermi wave vectors of Pd calculated by Mueller et al (1970), and Ev(x) was determined so as to satisfy (2). Then, k}l°(x) was obtained in the same way as in the first trial.…”

A qualitative study was made by electron diffraction of the short-range-order diffuse scattering from disordered Au-Pd, e phase Au-Zn, and e phase Ag-Mg alloys. Twofold and fourfold splittings of diffuse maxima are observed at 100, 110 and equivalent positions on the diffraction patterns with the incident beam parallel to [001], in the composition ranges from about 28 to 62 at.% Pd for Au-Pd, from about 7 to 24 at.% Zn for Au-Zn and from about 11 to 28 at.% Mg for Ag-Mg systems. The separation of the split diffuse maxima increases monotonically with Pd, Zn or Mg content. The results can be interpreted with the Fermi-surface-imaging concept proposed by Krivoglaz. The variation with composition of the Fermi wave vector parallel to the [110] directions is discussed with the nearly-free-electron and the rigidband models. The latter model is also applied to the experimental results for disordered Cu-Pd and Cu-Pt alloys reported by the present authors [Ohshima & Watanabe (1973), Acta Cryst. A29, 520-526].

“…Most heavy electron compounds have R W somewhat larger than the Kondo value of 2. [26,27] Systems with ferromagnetic enhancement can have significantly larger values of R W , such as Pd, where R W =6-8, [28] YbAgGe, where R W =2, [29] YbRh 2 Si 2 where R W =13, [30] and also Sr 3 Ru 2 O 7 where R W =10. [31] The magnitude of the zero temperature susceptibility in Yb 3 Pt 4 is comparable to those of the most enhanced heavy electron compounds, [27] although the Sommerfeld coefficient γ is several orders of magnitude smaller, implying an unreasonably large value for R W ∼3600.…”

We report the synthesis and basic properties of single crystals of a new binary compound, Yb3Pt4. The Yb ions in this compound are fully trivalent, and heat capacity measurements show that the crystal field scheme involves a doublet ground state, well separated from the excited states, which are fully occupied above ∼ 150 K. The heat capacity displays a large, weakly first order anomaly at 2.4 K, where a cusp is observed in the magnetic susceptibility signalling the onset of antiferromagnetic order. The entropy associated with this order is the full Rln2 of the doublet ground state, however the magnetic susceptibility in the ordered phase is dominated by a large and temperature independent component below the Neel temperature. The heat capacity in the ordered state originates with ferromagnetic spin waves, giving evidence for the inherently local moment character of the ordered state. The electrical resistivity is unusually large, and becomes quadratic in temperature exactly at the Neel temperature. The absence of analogous Fermi liquid behavior in the heat capacity and the magnetic susceptibility implies that Yb3Pt4 is a low electron density system, where the Fermi surface is further gapped by the onset of magnetic order.

“…The most prominent feature of the Pd vacuum XANES is the white-line at 3173 eV, caused by excitation of electrons from the 2p to the 4d band. 27 Although the atomic configuration of Pd is 4d 10 5s 0 hybridisation in the solid gives rise to 30 using ab initio calculations. Fig.…”

The electronic and geometric structure of the Pd/Ag-H system, an important hydrogen membrane structure, has been studied with x-ray absorption spectroscopy. Palladium L 3 XANES measurements in both vacuum and in situ under hydrogen atmosphere were performed at room temperature on an ideally mixed Pd 0.8 Ag 0.2 system obtained with bi-sputtering, and on a pure Pd system obtained with electroless plating. A model of fcc-Pd/Ag with the Ag atoms evenly distributed through the system and the hydrogen atoms placed in the octahedral holes was able to explain the observed XANES in great detail. FEFF calculations show that the Pd/Ag-H system generates an anti-bonding Pd-H band, in close agreement with the experimental results. In addition the calculations show that the hydrogen content of the system strongly influences the XANES, especially the intensity of the white-line and the anti-bonding peak. In contrast the influence of the Ag atoms is limited to relatively small changes in the white-line intensity. However change of the Ag distribution within the Pd/Ag fcc lattice from well-mixed to clustered was found to have a significant influence on the Pd L 3 edge white-line intensity.
