Physical properties of icosahedral and glassy PdUSi alloys
- Various physical properties have been measured on glassy, crystalline and on well-characterized quasicrystalline samples of the PdUSi system. In contrast to the strong differences observed between the static structure factors of quasicrystalline and glassy PdUSi samples, their dynamical properties, as revealed by neutron inelastic scattering, are nearly identical and quite different from those of the fully crystallized samples. The electronic structure has been investigated by photoelectron spectroscopy and the top surface layers have been probed by ion scattering spectroscopy. The general features of the valence electron structure in the quasicrystalline phase are very similar to those in the corresponding glassy alloy and similar intensities at the Fermi energy are observed. The electrical resistivity, the Hall coefficient and the magnetic susceptibility have been measured to high temperatures. The electronic transport and the magnetic properties in the icosahedral and glassy phases above room temperature are very similar. © 1988.
