A nuclear magnetic resonance study of Al-Mn quasicrystals and related materials

Nuclear magnetic resonance (NMR) results are presented for several aluminum alloy samples prepared using the melt-spinning technique including orthorhombic Al6Mn, Al-Mn quasicrystals both with and without doping with Si and Ru, and a T-phase alloy of A1 and Pt. With the exception of the orthorhombic material, all of the NMR spectra show a broad distribution of sites. No features unique to the quasicrystal phase are observed. For the orthorhombic material the quadrupole field parameters are found to be| vQ | = 1.0 ± 0.1 MHz and 77 = 0.4 + 0.1. © 1987, Materials Research Society. All rights reserved
