Summary
Common water ice is an unusual solid; the oxygen atoms form a periodic structure but the hydrogen atoms are highly disordered due to there being two non-equivalent O-H bond lengths. The presence of these two bond lengths leads to a macroscopic degeneracy of possible ground states. The authors present specific-heat data for an analogous system, dysprosium(2)-titanium(2)-oxygen(7). They also find, through application of magnetic field, behaviour not accessible in water ice-restoration of much of the ground-state entropy and new transitions involving transverse spin degrees of freedom.
