Effect of volume fraction on magnetoelectric coupling effect of Co0.1Cu0.9Fe2O4/Ba0.8Sr0.2TiO3 composite liquid

Effect of sintering temperature on magnetoelectric properties of PbTiO3/NiFe2O4 composite ceramics

“…Where ε 0 is the dielectric constant of vacuum (8.85 × 10 -12 F/m), ε r is the relative dielectric constant of the ceramic at 100 Hz test frequency, which is 1190. E = σ/ε 0 ε r , σ is the density of surface charge of a plate capacitor, which is equal to the value of remnant polarization of the sample [45,46]. Finally, the magnetoelectric coupling coefficient of ceramics is calculated to be 5.7 V/(cm•Oe).…”

Controlling magnetoelectric coupling effect of CoFe2O4–Ba0.8Sr0.2TiO3 multiferroic fluids by viscosity

“…24,25 The magnetic/polarization direction in multiferroic liquids is easier to change under an external field (electric field and magnetic field), resulting in a greater magnetoelectric coupling effect. 26 Wu 27 found that in Ba 0.8 Sr 0.2 TiO 3 -Co 0.5 Cu 0.5 -Fe 2 O 4 multiferroic fluids, magnetic-electric nanoparticles would form a chain structure under the action of a magnetic field and electric field. The number of chain structures and the interaction between chains will affect the magnetoelectric coupling effect.…”

Microstructure, Magnetodielectric, and Multiferroic Properties of xCo0.8Cu0.2Fe2O4−y(0.8BaTiO3–0.2BiAlO3) Composite Ceramics

“…Cobalt ferrite (CoFe 2 O 4 ) has been widely used as the magnetic phase in ME composites because of its unique properties, such as low eddy current loss, [ 9 ] high Curie temperature, [ 10 ] outstanding chemical stability, [ 11,12 ] and mechanical hardness, [ 13 ] as (1 − x )BaTiO 3 – x CoFe 2 O 4 , [ 14 ] x CoY 0.1 Fe 1.9 O 4 –(1 − x )Ba 0.95 Y 0.05 TiO 3 , [ 15 ] and 0.66BaTiO 3 –0.33Co 0.8 Zn 0.2 Fe 2 O 4 . [ 16 ] It was reported that the doping element and the doping levels can modify the electrical and magnetic properties.…”
