 note = {Low temperature magnetization measurements on the pyrochlore spin ice compound Dy2Ti2O7 reveal that the ice-rule breaking spin flip, appearing at H∼0.9  T applied parallel to the [111] direction, turns into a novel first-order transition for T<0.36   K which is most probably of a liquid-gas type. T-linear variation of the critical field observed down to 0.03 K suggests the unusual situation that the entropy release across the transition remains finite [∼0.5   (J/K)⋅mol−Dy] as T→0, in accordance with a breaking of the macroscopic degeneracy in the intermediate “kagomé ice” state.},
