Resumen

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.
