Researchers in Japan have identified a structural measurement that could help scientists predict magnetic behavior in complex alloys, offering a more reliable way to search for materials with unusual quantum properties.

The finding gives researchers studying quasicrystals and related materials a practical guide to selecting compounds for further investigation. These materials have intricate atomic arrangements that can support unconventional magnetism, making them useful subjects for exploring how atomic structure shapes collective behavior.
