摘要：

The magnetic spins of pyrochlore magnets are constrained to point either directly into or away from the centre of each structural building block. This is analogous to constraints on hydrogen ions in water ice. The discovery that the entropy of magnetic ‘spin ice’ and water ice are the same at low temperatures highlights a long-standing contradiction between the entropy of ice and the third law of thermodynamics.
