Abstract

27Al- and 63Cu-NMR measurements have been made on quasicrystalline phases of the Al65Cu20TM15 alloy (TM:Fe, Ru, and Os). There is no temperature dependence on peak shift and line width of either 27Al- or 63Cu-NMR spectra, suggesting that all the quasicrystalline phases are Pauli-paramagnetic. However, the peak shift of both spectra depends upon the constituent transition element in a different way: Al-peak shift increases from Fe through Os while the Cu-peak shift decreases.
