Atomic hopping in AlCuFe quasicrystal

High temperature 57Fe MOsshaner effect measurements in annealed icosahedral A1CuFe alloy are reported. The anomalous decrease in Debye-Waller factor is qualitatively interpretated. It is suggested using consistent parameters that the isomer shift decreases linearly with temperature in agreement w...

Atomic hopping in AlCuFe quasicrystal
description High temperature 57Fe MOsshaner effect measurements in annealed icosahedral A1CuFe alloy are reported. The anomalous decrease in Debye-Waller factor is qualitatively interpretated. It is suggested using consistent parameters that the isomer shift decreases linearly with temperature in agreement with a second-order Doppler shift in the Debye approximation.
