Spin Correlations in Ho${}_2$Ti${}_2$O${}_7$: a Dipolar Spin Ice System

S. T. Bramwell, M. J. Harris, B. C. den Hertog +8

The pyrochlore material $\mathrm{H}{\mathrm{o}}_2\mathrm{T}{\mathrm{i}}_2{\mathrm{O}}_7$ has been suggested to show ``spin ice'' behaviour. We present neutron scattering and specific heat results that establish unambiguou…
