Film formation : Polymer‐assisted deposition allows the growth of nanocomposite thin films comprising amorphous silica nanoparticles embedded in epitaxial SrTiO 3 and CoFe 2 O 4 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 CoFe 2 O 4 films greatly enhances its coercivity and magnetic anisotropy.
