Recent efforts have focused on exploring three-dimensional (3D) and curved magnetic nanostructures for nanoelectronics, sensorics, and computing, especially emphasizing spin textures and dynamics [1, 2]. However, studies on lattices of nanoarchitectures based on curved 3D elements are limited. Here we explore the properties of innovative, highly regular FeNi lattices of complex geometries [3]. A meticulous 3D reconstruction of the geometry coupled with modelling confirm that this system enables topologically non-trivial magnetic excitations in a high number. Dynamical measurements in combination with modelling confirm a switchable gap and local non-linear excitations. Overall, this system collects unique properties for becoming a captivating platform for advanced technologies in nanoelectronics and computing.
