Effects of the interlayer on the magnetic properties of Fe-Hf-C/ceramics multilayered films

The magnetic properties of nanocrystalline FeHfC single layered and FeHfC/ceramics (AlN, Al/sub 2/O/sub 3/, Si/sub 3/N/sub 4/, SiO/sub 2/) multilayered films were investigated. The soft magnetic properties of the multilayered films laminated by the Al-based ceramics were better, but those of films laminated by the Si-based ceramics were worse than the magnetic properties of single layered films. An analysis of multilayered structure revealed that FeHfC/AlN and FeHfC/Al/sub 2/O/sub 3/ films maintained better periodic structure than FeHfC/Si/sub 3/N/sub 4/ and FeHfC/SiO/sub 2/ films. The present results suggest that the interdiffusion effect plays an important role in determining the magnetic properties of the multilayered films.<
