Glass transition of spins and orbitals of electrons in a pure crystal

A joint research group from Osaka University and the University of Tokyo uncovered the mechanism of the glass transition that electrons can experience in pyrochlore oxide crystals. The researchers show that distortions in the atomic lattice cause two types of rotational degrees of freedom of spins to become coupled and form a glassy state at the exact same temperature. This work will shed light on our understanding of the mechanism of glass transitions, which is one of the most fundamental unsolved problems in physics.
