Diffuse polarized neutron scattering studies have been carried out on single crystals of pyrochlore spin ice Ho$$_{2-x}$$Y$$_{x}$$Ti$$_{2}$$O$$_{7}$$ (x = 0, 0.3, and 1) to investigate the effects of doping and anisotropy on spin correlations in the system. For all the samples studied the spin flip (SF) diffuse scattering (i.e. the in-plane component) reveals that the spin correlations can be described using a nearest-neighbour spin ice model (NNSM) at higher temperatures ($$T$$ = 3.6 K) and a dipolar spin ice model (DSM) as the temperature is reduced ($$T$$ = 30 mK). In this paper, we focus on the experimental results of the highly doped spin ice HoYTi$$_{2}$$O$$_{7}$$ and compare our results with pure spin ice Ho$$_{2}$$Ti$$_{2}$$O$$_{7}$$.
