Barium Ferrite Films Grown by Pulsed Laser Ablation
Perpendicular recording media with a high squareness in perpendicular M-H loop were developed by sputter-deposition. and their low noise property as well as high recording performances were confirmed The media with thicknesses of 30 to 200 nm were prepared on glass substrates by dc-magnetron sputtering using a Co-Crzo-Nb4 target Media of Co-Crz4 and Co-CrI8-Ta, were also prepared as the compari...
متن کاملRealization 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 ...
متن کاملCharacteristics of the surface layer of barium strontium titanate thin films deposited by laser ablation
Ba0.5Sr0.5TiO3 ~BST! thin films grown on Si by an in situ ultraviolet-assisted pulsed laser deposition ~UVPLD! technique exhibited significantly higher dielectric constant and refractive index values and lower leakage current densities than films grown by conventional PLD under similar conditions. X-ray photoelectron spectroscopy ~XPS! investigations have shown that the surface layer of the gro...
متن کاملMagnetic 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...
متن کاملHigh tunability in compositionally graded epitaxial barium strontium titanate thin films by pulsed-laser deposition
Compositionally graded barium strontium titanate @(BaxSr12x)TiO3—BST, x50.75, 0.8, 0.9, and 1.0# thin films are fabricated by pulsed-laser deposition on a LaAlO3 substrate with (La0.7Sr0.3)MnO3 as the bottom electrode. A high dielectric permittivity and temperature characteristic without Curie–Weiss law are obtained. A tunability of over 70% is obtained at frequency of 1 MHz, which is higher th...
