On the emergence of structure and transport properties in (Al50Mn50)100 −xCux

Abstract

In this contribution we report on emerging structure and transport properties of thin films of (Al50Mn50)100−xCux, evaporated at low temperature. Their structures have been investigated by electron diffraction, their transport properties and thermal stability by resistivity measurements, showing global resonance effects between two global subsystems, as there is the Fermi gas as one and the forming static structure of the remaining ions as the other one. The global resonances are self-organizing by the exchange of characteristic momentum, trigger density anomalies and hybridization effects, both reported in this contribution. We show strong indications for a combined action of density and an effective-valence anomalies, to keep the peak position on a resonance-preferred position in reciprocal space. In real space it causes the spherical structural periodicity of nearest-neighbor shells at medium-range distances. The spherical-periodic atomic order of an amorphous phase is analog to planar order in a crystal. The characteristic atomic distances between nearest neighbor shells are determined by the Friedel wavelength, half of the Fermi wavelength, indicating resonance effects. They influence all the properties including phase stability and electronic transport. The electronic transport properties and thermal stability data strongly correlate with the structural determination under global resonances.
