We have studied spin freezing in the diluted spin ice compound ${\mathrm{Dy}}_{2\ensuremath{-}x}{\mathrm{Y}}_{x}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ where the nonmagnetic Y ions replace the magnetic Dy ions on the frustrated pyrochlore lattice. Magnetic ac and dc susceptibility data are presented with an analysis of relaxation times for dilutions of $x=0,$ 0.1, 0.2, and 0.4. Site dilution apparently decreases the relative number of spins participating in the icelike freezing near 16 K while…
