Microstructure and magnetic properties of the CoPtRu-SiO2 single and CoPtRu-SiO2/Co72Pt28-SiO2 double layer nanocomposite films
In this work, the CoPtRu nanocomposite films with were fabricated on the Ru seed layer. The effects of Ru content on the microstructure and magnetic properties of the CoPtRu-SiO2 single layer nanocomposite films, and magnetic properties of the CoPtRu-SiO2/Co72Pt28-SiO2 double layer nanocomposite films were studied. Results showed that with an increase of Ru content in the CoPtRu film, the ordering degree of hcp-CoPtRu decreased, the volume of soft magnetic fcc phase increased, both the anisotropy constant and the saturation magnetization of the CoPtRu film decreased greatly. As a result, the anisotropy field of the film did not decrease notably. Therefore, the coercivity of the CoPtRu-SiO2/Co72Pt28-SiO2 double layer film was very close to that of Co72Pt28-SiO2 single layer film at both room temperature and low temperature.
