Iron nitride thin films have potential applications in the biomedicine and
energy. The magnetic properties of these films can be tuned by incorporating
copper nitride. In this study, iron copper nitride thin films have been
fabricated by magnetron sputtering technique either by co-sputtering iron
nitride and copper nitride or by layer stacking of the materials. The structure,
morphology and magnetic properties of the films have been studied by scanning
electron microscopy, x-ray diffraction, x-ray reflectivity and vibrating sample
magnetometry.
