      abstract     = {We present single-crystal magnetic diffuse
                      neutron-scattering measurements with polarization analysis
                      on the spin ice Ho2-xYxTi2O7 (x=0, 0.3, and 1). At 2 K, the
                      spin-flip scattering patterns are typical of a
                      nearest-neighbor spin ice and the effects of Y doping are
                      seen in the widths of the pinch points. At low temperature,
                      the spin-flip patterns are characteristic of a dipolar spin
                      ice and are unaffected by Y doping. In the nonspin-flip
                      channel, we observe the signature of strong
                      antiferromagnetic correlations at the same temperature as
                      the dipolar spin-ice correlations appear in the spin-flip
                      channel. These experimental observations have been well
                      reproduced by our Monte Carlo simulations.},
