Absence of Pauling’s residual entropy in thermally equilibrated Dy2Ti2O7
Abstract
Early specific-heat measurements of the archetypal spin ice Dy2Ti2O7 showed a residual entropy at low temperatures similar to that found in water ice. A technique exploiting slow thermal equilibration now reveals an absence of this entropy—calling into question the nature of Dy2Ti2O7 at low temperatures.
