Resumen:
Dy 2 Ti 2 O 7 is at present the cleanest example of a spin-ice material. Previous theoreticaland experimental work on the first-order transition between the kagome-ice and the fullypolarized state has been taken as a validation for the dipolar spin-ice model. Here we inves-tigate in further depth this phase transition using ac-susceptibility and dc-magnetization,and compare this results with Monte-Carlo simulations and previous magnetization andspecific heat measurements. We find signatures of an intermediate state between thekagome-ice and full polarization. This signatures are absent in current theoretical modelsused to describe spin-ice materials.
