- W1963515897 abstract "In order to test for the true intrinsic properties of icosahedral $itext{ensuremath{-}}mathrm{Al}text{ensuremath{-}}mathrm{Cu}text{ensuremath{-}}mathrm{Fe}$ quasicrystals, we performed investigations of magnetism, electrical resistivity, thermoelectric power, and thermal conductivity on a single-crystalline ${mathrm{Al}}_{64}{mathrm{Cu}}_{23}{mathrm{Fe}}_{13}$ quasicrystal grown by the Czochralski technique. This sample shows superior quasicrystallinity, an almost phason-free structure, and excellent thermal stability. Magnetic measurements revealed that the sample is best classified as a weak paramagnet. Electrical resistivity exhibits a negative temperature coefficient with ${ensuremath{rho}}_{4phantom{rule{0.3em}{0ex}}mathrm{K}}=3950phantom{rule{0.3em}{0ex}}ensuremath{mu}ensuremath{Omega}phantom{rule{0.2em}{0ex}}mathrm{cm}$ and $R={ensuremath{rho}}_{4phantom{rule{0.3em}{0ex}}mathrm{K}}∕{ensuremath{rho}}_{300phantom{rule{0.3em}{0ex}}mathrm{K}}=1.8$, whereas the thermopower exhibits a sign reversal at $T=278phantom{rule{0.3em}{0ex}}mathrm{K}$. Simultaneous analysis of the resistivity and thermopower using spectral-conductivity model showed that the Fermi energy is located at the minimum of the pseudogap in the spectral conductivity $ensuremath{sigma}(ensuremath{epsilon})$. Thermal conductivity is anomalously low for an alloy of metallic elements. Comparing the physical properties of the investigated single-crystalline ${mathrm{Al}}_{64}{mathrm{Cu}}_{23}{mathrm{Fe}}_{13}$ quasicrystal to literature reports on polycrystalline $itext{ensuremath{-}}mathrm{Al}text{ensuremath{-}}mathrm{Cu}text{ensuremath{-}}mathrm{Fe}$ material, we conclude that there are no systematic differences between the high-quality single-crystalline and polycrystalline $itext{ensuremath{-}}mathrm{Al}text{ensuremath{-}}mathrm{Cu}text{ensuremath{-}}mathrm{Fe}$ quasicrystals, except for the hindering of long-range transport by grain boundaries in the polycrystalline material. The so far reported physical properties of $itext{ensuremath{-}}mathrm{Al}text{ensuremath{-}}mathrm{Cu}text{ensuremath{-}}mathrm{Fe}$ appear to be intrinsic to this family of icosahedral quasicrystals, regardless of the form of the material." @default.
