We report the magnetoelectric, dielectric and magnetic properties of xCo0.7Zn0.3Fe2O4–(1 − x)Bi0.9La0.1FeO3 (x = 0.1, 0.2, 0.3 and 0.4) nanocomposites prepared by sol–gel method. The X-ray diffraction patterns of sintered pellets show the formation of composite phases. The average crystallite size obtain by Williamson–Hall plot for different nanocomposites were found to be in the range 70–80 nm, which are in agreement with particle size calculated from atomic force microscopy. Magnetoelectric voltage coefficient (αE = 315 mV/cm Oe) and the magnetocapacitance (MC = 3.1%) for x = 0.3 were found to be higher than other synthesized nanocomposites.
Graphical abstractPolycrystalline nanocomposites of xCo0.7Zn0.3Fe2O4–(1 − x)Bi0.9La0.1FeO3 (x = 0.1, 0.2, 0.3 and 0.4) were prepared by sol–gel method with average crystallite size in the range 70–80 nm as confirmed by AFM image. Magnetization (M) and magnetocapacitance (MC) were found to be enhanced for the nanocomposite.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Co0.7Zn0.3Fe2O4–Bi0.9La0.1FeO3 nanocomposites (grain size ∼ 90 nm) prepared by sol–gel method. ► Magnetization (M) was found 4.5% more than 0.4CoFe2O4–0.6BiFeO3 composite. ► Magnetocapacitance (MC) is observed higher compared to Ba doped BiFeO3. ► The value of αE was found to be 10% more than some reported.
