This talk will address the question on the ground state of real spin-ice systems. Spin-ice are magnetic systems, Dy2Ti2O7 to name one example, that are charaterised by big magnetic moments sitting on a pyrochlore lattice. At first instance, the interaction between these moments leads to magnetic frustration and the expectation of a extensively degenerate ice-like ground state. Theoretical work and recent experimental evidence put this naive expectation into question. In this talk I will discuss experimental work and numerical simulations on two different spin-ice systems, Dy2Ti2O7 and Ho2Ti2O7, that aim at elucidating the true ground state of spin-ice materials.
