Abstract: The structural, magnetic, and optical properties of mesoscale particles in the form of Au/Fe/Au layered disks and Ni@Au nanotubes have been studied. The disks were produced by electron-beam lithography followed by deposition of functional layers. Ni nanotubes were obtained by template synthesis using electrochemical deposition into pores of ion track membranes. They were removed from the templates and the resulting powders were covered with gold by chemical modification. Ferromagnetic structures coated with plasmonic metals demonstrate a high photothermal conversion efficiency in the region of plasmon resonance. Together with their magnetic properties, such as the vortex magnetic state, these structures are promising for biomedical applications.
