"We found that a disordered labyrinthine phase transforms into the more ordered parallel-stripe structure upon raising the temperature," said Yousra Nahas, first author of the study titled "Inverse Transition of Labyrinthine Domain Patterns in Ferroelectric Thin Films," published in the journal Nature. Former and present U of A physics researchers Sergei Prokhorenko, Bin Xu, Sergey Prosandeev, and Distinguished Professor Laurent Bellaiche, along with colleagues in France, also contributed to the study.

Proposed a century ago, these types of transitions seem to contradict the fundamental law that disorder increases with temperature. They have been found in other systems such as superconductors, proteins, liquid crystals and metallic alloys. But they had not...
