(a) A homogeneous magnetic field induced by a Halbach array of 9 mT is applied after the perfluorinated molds are filled. This allows the formation of maghemite dipolar chains. The fixation of the dipolar chains is achieved by the UV-crosslinking of the polymeric network. Reproduced with permission [66]. Copyright 2023, Wiley-VCH.
