| Abstract: | Magnetic nanogranular films can be applied widely to planar transformer, miniaturized planar inductor at very high frequency, electromagnetic interference suppression at microwave frequency and high frequency, carrier-type film magnetic field sensors in GHz band. These films have high saturation magnetization as metallic magnetic material, high resistivity near to that of ferrite and high real permeability from low frequency to microwave band. This paper comprehensively reviews the magnetic properties of several typical magnetic nanogranular films. |
