PERPENDICULAR ANISOTROPY IN FERRITE PLATED NiZn-FERRITE THIN 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 ...

Magnetic anisotropy and field switching in cobalt ferrite thin films deposited by pulsed laser ablation

We report the observation of contrasting magnetic behavior in cobalt ferrite CFO thin films deposited on single crystalline magnesium oxide MgO and strontium titanate STO . Epitaxial films on MgO 100 with a lattice mismatch of 0.35% showed out-of-plane anisotropy whereas the films on STO 100 with a lattice mismatch of 7.4% displayed in-plane anisotropy. Stress anisotropy calculated from angle-d...

PULSED LASER DEPOSITION OF Ni-Zn FERRITE THIN FILMS

Thin Ni0.5 Zn0.5 Fe2 O4 ferrite films were grown on different condition on different substrates using pulsed laser deposition technique. Studying the influence of the energy of the laser beam, of the O2 pressure, of the substrate temperature, and of the distance between the target and the substrate on the microstructure and on the magnetic properties were established optimal conditions for PLD ...
