Physicists discover ‘stacked pancakes of liquid magnetism’

Researchers have discovered a new phase of liquid magnetism in layered helical magnets, where magnetic dipoles behave like 'flattened puddles' with varying alignment between layers. This phenomenon, predicted by a computational model, may explain the unusual electronic behavior observed in these materials.
