摘要: Epitaxial spinel cobalt ferrite thin films have been prepared by spin-coating method. -axis in-plane and out-of-plane oriented are on a-plane c-plane sapphire substrates, respectively. The key process is to fabricate a layer of α-Fe2O3 precursor film first. final formed coating the with Cobalt nitrate solution subsequently activating topotactic reactive diffusion thermal annealing. In-plane magnetic anisotropy has confirmed in film. This enables fabrication epitaxial desired orientations without utilizing expensive physical vapor deposition systems.
