Chiral Coupling (IMAGE) Forschungszentrum Juelich Caption The spins (red and blue arrows) in distant magnetic layers can couple due to the discovered long-range interaction, which is illustrated as a white string connecting two spins. This coupling leads to a clockwise canting between the spins in the two layers. Its depicted mirror image with the opposite sense of canting is not found in the considered systems.
