Magnetic coupling phenomena in curved nanomagnets

Magnetic curvilinear objects possess new fundamental properties originating from the curvature-driven effects, leading to magnetochiral effects and topologically induced magnetization patterns. Recently, it was theoretically predicted that these effects come from the exchange-induced curvilinear interactions like anisotropy-like and chiral-like parts [R. Streubel et al., Magnetism in curved geometries (topical review), Journal of Physics D: Applied Physics 49 p. 363001 (2016)]. These recent developments ranging from theoretical predictions over fabrication of three-dimensionally curved magnetic thin films, hollow cylinders or wires, to their characterization using integral means as well as the development of advanced tomography approaches are in the focus of this talk.
