Abstract

(Figure Presented) Film formation: Polymer-assisted deposition allows the growth of nanocomposite thin films comprising amorphous silica nanoparticles embedded in epitaxial SrTiO₃ and CoFe₂O₄ matrices (see picture). These silica nanoparticles can be as small as 10 nm and become larger with increasing post annealing temperature. The incorporation of silica into epitaxial CoFe₂O₄ films greatly enhances its coercivity and magnetic anisotropy.
