The alloys Zr65Al7.5Ni10Cu7.3Fe 0.2Ag10 in the amorphous and icosahedral state have been studied with 57Fe Mössbauer spectroscopy in the temperature range 77-300 K. The average quadrupole splitting decreases with temperature as T3/2 and is significantly larger for the icosahedral alloy. The quadrupole splitting in the icosahedral alloy is the largest ever reported for a metallic system. The vibrations of the Fe atoms in both alloys are well described by a simple Debye model.
