Major directions in magnonics are the extension of magnonic conduits into the third dimension, and operations with short wavelength, fast moving exchange magnons. Both are addressed by direct write nanoarchitectures fabricated by focused electron beam induced deposition (FEBID). Characterisation results of 2D and 3D magnetic FEBID nanostructures by Brillouin light scattering (BLS) spectroscopy and ferromagnetic resonance (FMR) measurements are presented, including a structure with 3D hemicylindrical protrusion along the top face of the rectangular waveguide. The FEBID nanostructures exhibit strong magnetic response to quasi-static and dynamic external magnetic stimuli. Further characterisation of the material properties is foundational for advancing research into spin wave dynamics and geometric curvature induced effects on signal propagation.
