Focused-electron-beam-induced deposition is a promising technique forpatterning nanomagnets for spin qubit control in a single step. We fabricatecobalt nanomagnets in such a process, obtaining cobalt contents and saturationmagnetizations comparable to or higher than those typically obtained usingelectron-beam lithography. We characterize the nanomagnets using transmissionelectron microscopy and image their stray magnetic field using scanning NVmagnetometry, finding good agreement with micromagnetic simulations. Themagnetometry reveals the presence of magnetic domains and halo side-deposits,which are common for this fabrication technique. Finally, we estimate dephasingtimes for electron spin qubits in the presence of disordered stray fields dueto these side-deposits.
