Abstract

Dy$_2$Ti$_2$O$_7$ is at present the cleanest example of a spin-ice material.  Previous theoretical and experimental work on the first-order transition between the kagome-ice and the fully polarized state has been taken as a validation for the dipolar spin-ice model. Here we investigate in further depth this phase transition using ac-susceptibility and dc-magnetization, and compare this results with Monte-Carlo simulations and previous magnetization and specific heat measurements. We find signatures of an intermediate state between the kagome-ice and full polarization.  This signatures are absent in current theoretical models used to describe spin-ice materials.
