Abstract

Pulse laser deposition was used to investigate self-assembled BaTiO ₃-CoFe ₂O ₄ complex oxide nanostructures. A single ceramic target with the molar ratio of 0.62BaTiO ₃-0.38CoFe ₂O ₄ was used. The nanostructures, with CoFe ₂O ₄ nanopillars assembled in a BaTiO ₃ matrix are epitaxial in-plane and out-of-plane. The results show that the substrate temperature increases from 750 to 950°C and the average diameter of the pillars increased from ∼9 to ∼70 nm.
