ABSTRACTWe have grown thin films and multilayers of several ferrite materials with the spinel structure by pulsed laser deposition of stoichiometric targets. Epitaxial films can be grown on a variety of substrates including MgO, Al2O3, MgAl2O4, Y-stabilized ZrO2 (YSZ) and SrTiO3. Films on Mg- and Al-containing substrates have a low saturation Magnetization, Ms, while films on YSZ and SrTiO3 exhibit bulk values of Ms. The anisotropy can be lowered by a post growth anneal, resulting in a film with a permeability of 28.

Ferrite Thin Films

Cobalt ferrite thin films have been deposited on fused quartz substrates by pulsed laser deposition at various substrate temperatures, TS (25 °C, 300 °C, 550 °C and 750 °C). Single phase, nanocrystalline, spinel cobalt ferrite formation is confirmed by X-ray diffraction (XRD) for TS ≥ 300 °C. Conventional XRD studies reveal strong (111) texturing in the as deposited films with TS ≥ 550 °C. Bulk texture measurements using X-ray orientation distribution function confirmed (111) preferred orientation in the films with TS ≥ 550 °C. Grain size (13–16 nm for TS ≥ 300 °C) estimation using grazing incidence X-ray line broadening analysis shows insignificant grain growth with increasing TS, which is in good agreement with grain size data obtained from transmission electron microscopy.
