Abstract

In order to apply Fe-Co-B thin films for high-frequency magnetic devices, the thickness effects on the magnetic properties and microwave properties of these films have been studied. The complex permeability of these thin films has been measured at the frequency of 2GHz with cavity. The real part of the permeability μ^/ of the thin films increases with the decease of the thickness of the thin films because the decrease of the thickness of the thin films leads to the increase of the natural resonance frequency. The imaginary part of the permeability μ^// of the thin films exhibits a minimal value at 150nm thickness, which is due to the simultaneous effect of the natural resonance and eddy current effect. The FMR line width broadening can be observed with the increase of the thickness of the thin films from the FMR investigation, which supports the research results above.
