A microscopic model for the diluted spin-mixed compounds(R_xY_(1-x))_2BaNiO_5 (R=magnetic rare-earth) is studied using Quantum MonteCarlo (QMC). The ordering temperature is shown to be a universal function ofthe impurity concentration x and the intrinsic Ni-chain correlation length. Aneffective model for the critical modes is derived. The possibility of a quantumcritical point driven by the rare earth-concentration and the existence of aGriffiths phase in the high dilution limit is investigated. Several possibleexperimental approaches to verify the results are put forward.Comment: 4 pages, 3 figure
