Dense multiferroic 0‐3 type composites encompassing BaTiO 3 and Y 3 Fe 5 O 12 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 Y 3 Fe 5 O 12 ferrimagnetic phase well dispersed in the tetragonal BaTiO 3 ferroelectric matrix. Raman spectroscopy analyses corroborate the polar nature of the BaTiO 3 matrix in composites with a Y 3 Fe 5 O 12 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 Y 3 Fe 5 O 12 content.
