Abstract[EN] Dense multiferroic 0-3 type composites encompassing BaTiO and YFeO were fabricated by the solid-state reaction method. X-ray diffraction data combined with scanning electron microscopy imaging show virtual immiscibility between the two phases, with the YFeO ferrimagnetic phase well dispersed in the tetragonal BaTiO ferroelectric matrix. Raman spectroscopy analyses corroborate the polar nature of the BaTiO matrix in composites with a YFeO content as great as 40 wt%. Ferrimagnetism is detected in all composites and no additional magnetic phases are distinguished. Although these dense ceramics can be electrically poled, they exhibit a very weak magnetoelectric response, which slightly increases with YFeO content.
