EFFECTS OF THE INTERLAYER ON THE MAGNETIC-PROPERTIES OF FE-HF-C CERAMICS MULTILAYERED FILMS

Abstract

The magnetic properties of nanocrystalline single layered and FeHfC/ceramics (AlN, Al2O3, Si3N4, SiO2) 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/Al2O3 films maintained better periodic structure than FeHfC/Si3N4 and FeHfC/SiO2 films. The present results suggest that the interdiffusion effect plays an important role in determining the magnetic properties of the multilayered films.
