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.

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.

The bioactive properties of hydroxyapatite (HA) are well known in the implant industry and coatings of HA have been used to enhance the adhesion of living tissue to metal prostheses. Pulsed laser deposition (PLD) in a water vapour atmosphere is an appropriate method for the production of crystalline HA coatings. In this work the effect of RF plasma on thin films of HA grown by PLD at different substrate temperatures has been studied. The physicochemical properties of the films were studied by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS), showing that the incorporation of RF discharge in the deposition chamber can lead to changes in the crystallinity and deposition rate of the films but substrate temperature still plays the most important role.
