• W2051796776 abstract "Amorphous ${mathrm{Zr}}_{x}{mathrm{Cu}}_{1ensuremath{-}x}$ alloys ($0.50ensuremath{le}xensuremath{le}0.74$) prepared by melt-spinning are investigated by means of electrical and thermal measurements. The negative temperature coefficient of the electrical resistivity suggests that the criterion $2{k}_{F}ensuremath{approx}{k}_{p}$ is always fulfilled in this system [${k}_{F}$ is the Fermi wave number, ${k}_{p}$ is the position of the first maximum of the structure factor $S(k)$]. The high density of states ${N}_{ensuremath{gamma}}({E}_{F})$ as inferred from specific-heat measurements originates from the $d$ electrons of Zr. The bare density of states [determined from ${N}_{ensuremath{gamma}}({E}_{F})$ with the aid of the electron-phonon coupling constant $ensuremath{lambda}$] is 3 times higher than that calculated from the free-electron model and almost independent of the Zr concentration. Phonon-electron scattering as determined by thermal-conductivity measurements shows a similar deviation from free-electron behavior. A decisive test of the Nagel-Tauc condition for high (meta-) stability of the metallic glasses is not possible due to the apparent failure of both free-electron and rigid-band models. All samples investigated are superconducting and belong to the extreme-type-II superconductors. Fluctuation-induced paraconductivity extends up to $1.5{T}_{c}$. An analysis of the electron-phonon coupling constant $ensuremath{lambda}$ as determined from ${T}_{c}$ indicates that the electron-ion matrix element $〈{I}_{2}〉$ varies strongly across the ${mathrm{Zr}}_{x}{mathrm{Cu}}_{1ensuremath{-}x}$ series. The size of $ensuremath{lambda}$, the jump of the specific heat at ${T}_{c}$, and its drop at low temperatures show that Zr-Cu alloys are weak- to intermediate-coupling superconductors. The relatively high ${T}_{c}$ values of the Zr-rich metallic glasses allow the observation of a linear specific-heat term for $Tensuremath{ll}{T}_{c}$ in all these samples which is due to localized low-energy excitations. These excitations are also seen---via strong phonon scattering---in the thermal conductivity." @default.
