Abstract
The 27Al and the 55Mn 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 55Mn resonance in orthorhombic Al6Mn have been determined as |vQ| = 0.76 MHz,Kax = −2.7 × 10−4, Kiso = + 5 × 10−3. The results imply that Al6Mn and the quasiperiodic crystals have similar electronic and magnetic properties.Keywords
