The most effective couplings have been found to occur between the magnetic layers in a vertical stack. We achieved strong coupling of laterally adjacent nanomagnets using the interfacial Dzyaloshinskii-Moriya interaction. This coupling is mediated by chiral domain walls between out-of-plane and in-plane magnetic regions and dominates the behavior of nanomagnets below a critical size. We used this concept to realize lateral exchange bias, field-free current-induced switching between multistate magnetic configurations as well as synthetic antiferromagnets, skyrmions, and artificial spin ices covering a broad range of length scales and topologies. Our work provides a platform to design arrays of correlated nanomagnets and to achieve all-electric control of planar logic gates and memory devices. application/pdf https://sonar.ch/global/documents/291806 eng info:eu-repo/semantics/altIdentifier/doi/10.1126/science.aau7913 info:eu-repo/semantics/altIdentifier/pmid/30923219 info:eu-repo/semantics/openAccess Science (New York, N.Y.). - 2019 Multidisciplinary Chirally coupled nanomagnets. http://purl.org/coar/resource_type/c_6501
