Physicists at the University of Toronto have discovered a way to detect "octupolar" magnetism, a complex magnetic state featuring eight poles instead of the usual two found in standard magnets. While most magnets operate as simple dipoles with north and south poles, this new form of order was previously invisible to conventional measurement tools. The research team led by Professor Arun Paramekanti developed a method using light to observe atomic vibrations caused by spinning electrons, marking a critical first step toward applying these states in future data storage and computing technologies.<\/p>\n

The study focused on "phonons," which are packets of vibrational energy moving through a material’s crystal structure. The researchers looked for "chiral phonons," a type of vibration that has a specific handedness, similar to how a left hand does not fit over a right hand even though they are mirror images. By shining special rotating light on the materials, the team observed unique vibrations known as "pseudo-chiral" phonons. These vibrations carry a distinct signature that reveals the presence of hidden octupolar magnetic states, which behave differently than those in conventional magnets.<\/p>\n

Professor Paramekanti noted that their work identifies new signatures for this hidden magnetic state, while co-author Swati Chaudhary explained that these vibrations impart a specific handedness to certain phonon modes. This optical fingerprint allows scientists to identify and study magnetic orders that are difficult to detect using standard techniques. The findings, published in Physical Review Letters in 2026, provide a new foundation for controlling magnetism through atomic vibrations, potentially enabling controllable read-write memory elements for everyday computers.<\/p>\n
