In this research, the formation of thin layers of magnetoelectric nanoparticles (MENPs) by inkjet print is presented. First, the MENPs based on ≈ 9 nm magnetostrictive CoFe2O4 ferrite cores coated with ferroelectric BaTiO3 shell (CoFe2O4@BaTiO3) were synthetized and a stable dispersion suitable for inkjet printing was prepared. Then, printing tests were carried out at resolutions of 1270 dpi, 1680 dpi, and 2540 dpi on glass and PET substrates. To evaluate the effect of the number of printed layers, samples containing 5, 10, and 20 layers were prepared. The aim of this study was to assess the influence of printing parameters and substrate type on the quality and morphology of the resulting films. The printed structures were characterized using atomic force microscopy (AFM), contact profilometry, and optical microscopy. The results demonstrate that both printing resolution and the number of layers affect the final thickness and surface morphology of the printed films, with noticeable differences observed between glass and polymer substrates. The variation in printing resolution and number of deposited layers resulted in film thicknesses ranging from 0.1 ± 0.1 µm (at 1270 dpi) to 4.0 ± 0.9 µm (at 2540 dpi) on PET substrates, and from 0.2 ± 0.08 µm to 4.0 ± 0.05 µm on glass substrates, respectively.
