Abstract

The effects of a Pt underlayer and a Pt interlayer on the textured growth of the sputtered strontium ferrite (SrM) films were investigated. The structural and magnetic properties of SrM films on the Pt underlayers were compared with SrM films on thermally oxidized Si substrates. It was found that much better (001) texture was obtained on the films with Pt underlayers, as indicated by the strong (006), (008) and (0014) reflections from X-ray diffraction (XRD) measurement. A Pt interlayer was also found to further improve the (001) texture
