Ceramic composites (x BaTiO 3 -(1-x) Fe 3 O 4 ) were successfully prepared by a direct solid state reaction of raw materials (BaCO 3 , Fe 3 O 4 , and TiO 2 ). X-ray diffraction (XRD) and electron probe micro analysis (EPMA) measurements were performed for these samples and it is confirmed that the composites consist of

(1-x)BaTiO 3 -xFe 3 O 4 composites were successfully prepared by conventional solid-state sintering of raw materials (BaCO 3 , TiO 2 , and Fe 3 O 4 ) in the molar fraction x of Fe 3 O 4 to BaTiO 3 at 1323 K for 5 hours under Ar gas flow. X-ray diffraction (XRD) and electron probe micro analysis (EPMA) measurements were performed for these samples and it is confirmed that the composites consist of only two phases of
