N2 - The magnetic correlations in "stuffed" spin ice Ho2+x Ti2-x O7-δ have been characterized using quasielastic neutron scattering. At temperatures above 1 K, these correlations are short ranged in nature and dynamic on a picosecond to nanosecond time scale. As for the case of pure spin ice Ho2 Ti2 O7, one can identify, above the freezing temperature, a quantum relaxation regime which is enhanced as it persists to even higher temperatures, T∼30-40 K, than in the parent compound.
