  "abstract": "The consecutive magnetic ordering of the Ho and Ru ions in the pyrochlore Ho₂Ru₂O₇ and their interplay are investigated by neutron scattering, magnetic, and specific heat measurements. The Ru moments order at 95 K into a Γ₅ easy-plane antiferromagnetic state. At 1.55 K, the Ho moments order into an unusual Γ₉ ferromagnetic state with extensive ground state entropy and structured spin dynamics. It is shown how the internal fields with Γ₅ and Γ₉ geometry allow for two symmetry breaking transitions. The lower temperature ordering is driven by ruthenium mediated interactions between holmium moments as spin ice correlations develop. The unsaturated order is compatible with a fragmented ferromagnetic state equivalent to pyrochlore kagome ice.",
