Abstract

DC magnetization of Dy₂Ti₂O₇ has been measured down to 30 mK. The ice-rule breaking spin flip appearing at H∼0.9 T(||[111]) turns into a first-order transition for T<0.36 K which is most probably of liquid-gas type. T-linear variation of the critical field suggests that the entropy release across the transition remains finite (∼0.5 J/K molDy) down to 0.03 K, confirming the macroscopic degeneracy in the intermediate 'kagomé ice' state.
