The structure of the μ‐Al 4 Mn phase, which is an approximant of icosahedral and decagonal quasicrystals, is interpreted as a modulated crystal structure. It basically comprises modulated layers, in which the ordering of atomic vacancies takes place in the close‐packed layers. The modulation is considered to be due to the rearrangement of atomic vacancies as a response to the occurrence of charge‐density waves.
