Herein, this work reports a DMI\u2010like behavior in permalloy via coupled vortices in confined structures. Under the in\u2010plane magnetic fields, continuous reversals of different coupled vortices are directly observed by in situ Lorentz transmission electron microscopy, and reproduced by complementary micromagnetic simulations. The statistical results show that coupled vortices with opposite chirality appear more frequently with the frequency up to about 60%. Such an asymmetric phenomenon mainly arises from a DMI\u2010like behavior, associated with the increased total energy difference between different ground\u2010state coupled vortices. Moreover, in the reversal process, the junction between disks accelerates the annihilation of vortices moving toward it and is also the starting point of vortex nucleation. These results provide an effective method to generate a DMI\u2010like behavior in magnetic systems with symmetry breaking surface and benefit the future development of vortex\u2010based spintronic devices.<\/jats:p>","DOI":"10.1002\/smll.202207206","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T07:18:47Z","timestamp":1672989527000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Dzyaloshinskii\u2013Moriya\u2010Interaction\u2010Like Behavior in Confined Permalloy Nanostructures via Coupled Magnetic Vortices"],"prefix":"10.1002","volume":"19","author":[{"given":"Chenglong","family":"Hu","sequence":"first","affiliation":[{"name":"Key Laboratory for Anisotropy and Texture of Materials (MOE) School of Materials Science and Engineering Northeastern University  Shenyang 110819 P.
