| Abstract: | Three-dimensional (3D) magnetic nanostructures promise exciting opportunities beyond the physics of planar systems, with prospects for new topological textures [1], curvilinear effects [2], non-reciprocal dynamics [3] and ultrafast texture motion. Yet, investigating dynamics in complex 3D nanogeometries has remained challenging due to limitations in fabrication and characterization. Here, we combine direct 3D nanoprinting [4], lab-based magnetic imaging, and time-resolved X-ray microscopy [5] to experimentally uncover the dynamics in cobalt nano double helices [6]. First, we observe resonant dynamics of coupled domain walls in real space and time, while micromagnetic simulations reveal the origin of the observed resonances and predict additional higher-frequency modes tunable though geometry. By engineering the double helix geometry, the magnetostatic coupling strength and resonant frequ |
