Abstract

Well oriented CoTi-substituted Ba-ferrite thin films, with c-axis perpendicular to the film plane, have been produced by pulsed laser deposition on (0001) sapphire substrates at 840 °C. These films were of good optical quality and exhibited optical and magneto-optical properties similar to the bulk single crystal material. Furthermore, angular thickness variations caused by narrow plume distributions were studied by depositing onto glass substrates and correlating variations in reflectance with thickness variations through optical interference effects. The surface morphology of the ceramic Ba-ferrite targets after progressive laser illumination was studied by scanning electron microscopy.
