Abstract
An Al-27 NMR study of mixed yttrium-dysprosium-aluminum garnets Y3-xDy xAl5O12 is reported far x = 0, 0.15, 0.50, 0.64, and 1.00. The quadrup ole coupling parameters for the a and d aluminum sites have been deter mined. The spectra have been theoretically calculated with inclusion o f the paramagnetic shift induced by Dy3+ ions. An analysis of the NMR line shape has permitted a conclusion that there is no substitutional order in the mixed crystals under study. (C) 1998 American Institute o f Physics.
