27 Al NMR studies of the Y 3— x Yb x Al 5 O 12 mixed garnets were performed. The magnetic moment of Yb 3+ ions in the garnets was determined. The quadrupole coupling 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 partially ordered solid solutions. A model of substitutional ordering for these mixed garnets was suggested.
