| The ice configuration possessing the most flippable plaquettes is the squiggle state, shown here within a 40-site tetragonal cell. Arrows show the displacement of protons within Ic water ice or, equivalently, the orientation of spins in spin ice. The squiggle state possesses a net magnetic flux, orientated along a [100] axis. |
