Abstract
Al-27 NMR studies of the Y3-xYbxAl5O12 mixed garnets were performed. The ma gnetic moment of Yb3+ ions in the garnets was determined. The quadrupole co upling constants were calculated for Al in a- and d-positions. It was shown that the mixed garnets with x = 0.75 and 1.00 should be treated as partial ly ordered solid solutions. A model of substitutional ordering for these mi xed garnets was suggested.
