Abstract

Self-assembled epitaxial nanocomposite CoFe ₂O ₄:SrTiO ₃ and CoFe ₂O ₄:MgO thin films were grown on LaAlO ₃ substrates by a chemical solution approach of polymer-assisted deposition. X-ray diffraction and transmission electron microscopy analyses indicated that both phases in the composites were epitaxial with respect to the major axes of the substrate. Compared to the single-phase ferrimagnetic spinel CoFe ₂O ₄ films and the bilayer CoFe ₂O ₄/SrTiO ₃ and CoFe ₂O ₄/MgO films, the composite films exhibited reduced coercivity and enhanced magnetic anisotropy.
