Curvilinear Magnetism: Fabrication and characterization — •Denys Makarov — Helmholtz-Zentrum Dresden-Rossendorf e.V., Institute of Ion Beam Physics and Materials Research, 01328 Dresden, Germany

Extending 2D structures into 3D space has become a general trend in multiple disciplines including electronics, photonics, and magnetics. This approach provides means to enrich conventional or to launch novel functionalities by tailoring curvature and 3D shape. We realize 3D curved magnetic thin films where new fundamental effects emerge from the interplay of the geometry of an object and topology of a magnetic sub-system [1]. The application potential of 3D magnetic architectures is explored for the realization of mechanically shapeable magnetoelectronics [2] for virtual and augmented reality appliances [3,4]. To advance in this research field, we develop novel theoretical methods [5-7], fabrication [1,8,9] and characterization techniques [8-11]. These topics will be addressed in the presentation.
