Nonuniform local magnetism in Al-Mn quasicrystals
Abstract
The distribution of local magnetism in Al-Mn quasicrystal alloys has been studied by NMR spin-echo techniques. The 55Mn resonance is found to be close to the position observed in nonmagnetic orthorhombic Al6Mn and α-Al73Si10Mn17 despite large paramagnetic susceptibilities in the quasicrystals. Analysis of spectral intensities shows that the paramagnetism is due to a class of Mn sites having local environments which do not occur in the crystals.
