Abstract
Three-dimensional (3D) nanomagnetic devices such as the vertical racetrack
memory have attracted a huge interest due to their potential for memory and
logic applications. However, their implementation has not been realised due to
great challenges regarding fabrication and characterisation of 3D
nanostructures. Here, we show a 3D nanomagnetic system created by 3D
nano-printing and physical vapour deposition, which acts a conduit for domain
walls. Domains formed at the substrate level are injected into a 3D nanowire,
where they are controllably trapped using vectorial magnetic fields. A
dark-field magneto-optical method for parallel, independent measurement of
different regions in individual 3D nanostructures is also demonstrated. This
work opens a new route for the advanced study and exploitation of 3D
nanomagnetic systems.
