      abstract     = {The exchange interaction governs static and dynamic
                      magnetism. This fundamental interaction comes in two
                      flavours—symmetric and antisymmetric. The symmetric
                      interaction leads to ferro- and antiferromagnetism, and the
                      antisymmetric interaction has attracted significant interest
                      owing to its major role in promoting topologically
                      non-trivial spin textures that promise fast,
                      energy-efficient devices. So far, the antisymmetric exchange
                      interaction has been found to be rather short ranged and
                      limited to a single magnetic layer. Here we report a
                      long-range antisymmetric interlayer exchange interaction in
                      perpendicularly magnetized synthetic antiferromagnets with
                      parallel and antiparallel magnetization alignments.
                      Asymmetric hysteresis loops under an in-plane field reveal a
                      unidirectional and chiral nature of this interaction, which
                      results in canted magnetic structures. We explain our
                      results by considering spin–orbit coupling combined with
                      reduced symmetry in multilayers. Our discovery of a
                      long-range chiral interaction provides an additional handle
                      to engineer magnetic structures and could enable
                      three-dimensional topological structures.},
