Multiferroic BaTiO3-CoFe2O4-BaTiO3 thin films were synthesized by spin coating of Co(NO3)2 – Fe(NO3)3 and Ba(OAc)2 – Ti(i-OPr)4 solutions in a solvent mixture of acetic acid and dimethylformamide. Subsequent stepwise thermal treatment at 200, 400 and 800 °C leads to the desired fe...
The BatiO3/CoFe2O4 particulate composites were synthesized using a one-pot process. Particulate CoFe2O 4 phase is embedded in the BaTiO3 matrix homogeneously with 3-0 connectivity via a phase segregation mechanism. It was observed that the magnetoelectric voltage coefficient, αE, increased with ...
The nanocomposite xCoFe 2 O 4 -(1−x)BaTiO 3 (x=0.2, 0.3, 0.4, 0.5, molar fraction) fibers were prepared by the organic gel-thermal decomposition process, and the process was described in detail in Refs.[9−10]. The
