Electrophoretic Deposition of CoFe2O4 Nanograins Dispersed in a Laser Ablated BaTiO3 Matrix
Thin film nanocomposites composed by CoFe 2 O 4 grains, deposited by electrophoresis, and subsequently covered by a laser ablation deposited BaTiO 3 layer, were prepared with different cobalt ferrite concentrations (x). The cobalt ferrite phase was under a compressive strain that relaxed as the CoFe...
