This paper describes the recent progress of high-frequency micromagnetics in the ICT field. As a new magnetic thin film material for RF applications, CoFeSiO granular/SiO ₂ insulator multilayer film is shown, which has a good high-frequency magnetic properties with 2.4 GHz ferromagnetic resonance and very narrow resonance linewidth. As the RF applications, two topics are shown, one is the CoFeB magnetic thin film directional coupler with broadband operation, the other is a negative permeability application to suppress the skin effect of signal line in the RF devices. Finally, the voltage-driven magneto-optic spatial light modulator with magneto-photonic crystal and PZT film is described.
