Abstract

27Al and55Mn nuclear magnetic resonance shift, K, and27Al spin lattice relaxation time, T1, have been measured for the six-dimensional face-centered icosahedral quasicrystals, Al75-xPd15Mn10+x with x=0, 2 and7. The Al75Pd15Mn10 quasicrystal exhibits a temperature independent Knight shift K and(T1T)-1=0.022±0.002 (K s)-1 in a temperature range from room temperature to 5 K because there exist no Mn atoms with local magnetic moment. The replacement of Al with Mn drastically decreases the27Al K, the55Mn K and T1 of27Al, andthe27Al K becomes negative. There is an additional contribution to the spin lattice relaxation time independent of temperature. This is considered to be due to the presence of a localized magnetic moment in the replaced Mn atoms.
