Researchers find liquid-crystal-like magnetism in a rare-earth ytterbium compound
A team led by Pengcheng Dai at Rice University published findings on October 8, 2026, describing how quantum spins in an ytterbium compound behave like liquid crystals.
Spins show preferred direction without order
The study reveals that quantum spins in the material favor a specific orientation. Unlike ordinary magnets, these spins do not line up to create large-scale magnetization. This behavior mimics the rod-shaped molecules found in liquid crystal displays.
New state challenges previous theories
Earlier research suggested that some magnetic compounds might host an intermediate spin nematic state. The new data confirms this possibility exists within YbMnBi₂. The results help explain puzzling properties in the rare-earth element compound.
