英文摘要 |
In this paper we report a ferromagnetic resonance (FMR) study on a series of granular Nix-(SiO2)1-x film with the Ni volume fraction x ranging from 0.24 to 1.0. The x-dependence of the resonance field and of the linewidth were examined with field applied parallel and perpendicular to the film surface. Our results show that the shape anisotropy of the Ni-grains increases systematically with increasing x and that the magnetic coupling between the grains is greatly enhanced at the percolation threshold. |
