Growth of Magnetic Tips by Focused Electron Beam Induced Deposition (FEBID)

ORAL

Abstract

The focused electron beam induced deposition (FEBID) technique allows the direct growth of material on any substrate, including cantilevers used in scanning probe microscopy (SPM). Magnetic tips for SPM can be grown by FEBID using precursors of magnetic materials, such as Co2(CO)8 and Fe2(CO)9 [1]. In the current work, we report on the growth conditions to achieve optimized SPM magnetic tips by FEBID for three different applications. In the first application, cobalt magnetic nanospheres are grown for ferromagnetic resonance force microscopy [2]. In the second application, long (10 μm) cobalt nanowires are grown for nanowire magnetic force sensors [3]. In the third application, sharp iron tips are grown for magnetic force microscopy [4]. Novel developments and applications in the field will be discussed.
