文摘

Self-assembled epitaxial nanocomposite CoFe₂O₄:SrTiO₃ and CoFe₂O₄:MgO thin films were grown on LaAlO₃ 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 CoFe₂O₄ films and the bilayer CoFe₂O₄/SrTiO₃ and CoFe₂O₄/MgO films, the composite films exhibited reduced coercivity and enhanced magnetic anisotropy.
