With the rapid development of high-tech fields such as electronics, communications, military and aerospace, there is an urgent need for high-performance electromagnetic absorbing materials. Fe-Ni alloys and W-type ferrites have excellent magnetic and conductive properties, and therefore, making them into absorbing materials can greatly improve their absorption performance. In this study, sol-gel method will be used to prepare Fe-Ni alloy and W-type ferrite nano-particles, and then the nanocomposite materials will be prepared into thin films by magnetron sputtering technology. The structure characterization and absorption property testing of the thin film samples will be carried out to explore the relationship between absorption properties and structure. The expected research results can provide new ideas and new materials for the study of high-performance absorbing materials.Keywords: Fe-Ni alloy, W-type ferrite, nanocomposite materials, absorption properties
