Multiferroic Properties of Nanopowder‐Synthesized Ferroelectric‐Ferromagnetic 0.6BaTiO3‐0.4NiFe2O4 Ceramic

“…However, due to low Neel temperature, it is difficult to use them in practical devices [3][4][5]. As a possible alternative, laminated ferromagnetic/ferroelectric composites have received much interest with regard to product properties [6,7]. The multiferroic effect in a composite ceramic or laminated structure has a multiferroic coupling constant two or three orders higher than that in single phase structures [6,7].…”

“…However, the laminated structure is limited by the feature size, miniaturizing difficulties, and brittleness. Composites ceramics are limited by their high dielectric loss, often higher than 1, which is not good for practical applications [7]. The high dielectric loss should be attributed to the interface reaction at high sintering temperature and the low resistance of the magnetic phase.…”

Frequency dependent Dielectric Properties of Ni-Zn-Co ferrite and Barium Titanate ferroelectric ME composites

“…Magnetoelectric effect is a product property of two phases (ferrite and ferroelectric) in which the material becomes magnetized when placed in an electric field and electrically polarized when placed in a magnetic field. Due to ability of magnetoelectric conversion these ME composites are used in electronic devices as transducer, sensors, attenuator, band pass filter , phase shifters , broad band /wide band sensor , microwave application and ME memory applications [2][3][4][5][6][7][8][9] . The purpose of this study is to realize the increase in resistivity of composites for gettings high ME voltage coefficient.…”
