Liquid-crystal-like magnetism explains puzzling properties in a rare-earth compound

What happened

have discovered that in one compound containing the rare-earth element ytterbium, these spins can behave much like the molecules in a liquid crystal: favoring a certain direction without lining up to create magnetism on larger scales. In some materials, physical properties don't emerge from their individual particles, but from the collective behavior of their quantum spins. Now, researchers led by Pengcheng Dai at Rice University in the U.S.
