摘要：

The Al-27 and the Mn-55 nuclear magnetic resonance powder pattern lineshapes have been obtained in icosahedral and decagonal (T phase) Al-Mn quasiperiodic crystals, and are compared to that of orthorhombic Al6Mn. The quasiperiodic crystals yield much broader spectra with little resolved structure. The quadrupole and Knight shift parameters for the Mn-55 resonance in orthorhombic Al6Mn have been determined as vertical bar nu(Q) vertical bar = 0.76 MHz, K-ax = - 2.7 X 10(-4), K-iso = + 5 X 10(-3). The results imply that Al6Mn and the quasiperiodic crystals have similar electronic and magnetic properties.
