M-Type Barium Hexagonal Ferrite Films

Thin films of barium ferrite with perpendicular magnetic anisotropy produced by laser ablation deposition

Barium ferrite thin films with perpendicular magnetic anisotropy have been prepared on heated (001) sapphire substrates by laser ablation deposition in an oxygen atmosphere using a KrF excimer laser. X-ray diffraction patterns reveal highly oriented films of the magnetoplumbite phase with a c-axis angular spread of 1.8”. Scanning electron micrographs reveal that these films are polycrystalline ...

Titanate nanotube thin films via alternate layer deposition.

Layer-by-layer growth of titanate nanotubes on glass substrates was achieved by alternate layer deposition using an aqueous solution of colloidal titanate nanotubes and that of a polycation. Even a single layer thin film of titanate nanotube shows high photoinduced hydrophilicity.

Realization of hexagonal barium ferrite thick films on Si substrates

Hexagonal barium ferrite thick films (50–200μm) have been deposited on Si and Al2O3/Si substrates using a screen printing technique. X-ray diffractometry, scanning electron microscopy and magnetometry were used to characterize and correlate the ferrite films’ microstructure and magnetic properties. The experiments indicated that an Al2O3 underlayer was effective in preventing silicon diffusion ...
