Self-assembled epitaxial nanocomposite BaTiO3-NiFe2O4 films prepared by polymer-assisted deposition

We present a new approach, cost-effective polymer-assisted deposition, to prepare self-assembled epitaxial BaTiO3-NiFe2O4 nanocomposite films on LaAlO3 substrates. Ferroelectric BaTiO3 is embedded in the ferrimagnetic spinel NiFe2O4 matrix. The composite shows both ferroelectric and ferrimagnetic properties.
