Abstract

The magnetic and structural properties of BaFe12O19 films prepared by sputtering are compared with samples deposited using laser ablation deposition (LAD). Both techniques yield as-deposited films that are without crystal structure and consequently non-magnetic. The development of crystal structure and associated magnetic properties after rapid thermal processing (RTP [1]) and ultra-rapid thermal processing using a CO2 laser is presented. Early results indicate that control of the oxygen content of the material is of critical importance during both preparation and subsequent processing. Provided this control is present a material with a significant perpendicular magnetic anisotropy can result from very rapid thermal processing.
