• FEBID is the metal content, which is generally linked to the functionality of the deposit. In the case of magnetic deposits grown by FEBID, the metal content can be finely tuned in various ways. The beam current [7][33], the beam dwell time [30], the precursor flux [5], the beam voltage [34] and the

• substrate temperature [35][36] have been found to be relevant parameters to tune the metal content in magnetic deposits. However, some constraints exist, which impede to grow arbitrary shapes with arbitrary metal content. In general, the difficulties increase when the goal is to grow very small structures
