Physicists Use Rotating Light to Reveal Hidden Eight-Pole Magnetism in

University of Toronto-led physicists have shown that hidden octupolar magnetic order leaves a detectable handedness signature in a crystal's chiral phonons, which rotating light can read, opening a path toward new quantum memory technologies.

Physicists Identify 'Octupolar' Magnetism, With Implications for Quantum Technologies

While most magnets have two poles (north and south, or positive and negative), recent advances in quantum mechanics have revealed an "octupolar order," writes Phys.org, where a pattern of particles in a crystalline structure "behaves as if it has eight magnetic poles rather than the familiar two." ...
