Magnetic resonance properties for ECC nano-pillar were numerically analyzed. The analysis showed there are three resonance modes in the ECC nano-pillar that ferromagnetic resonances (FMR) at the low and high frequency regions associating with the soft and hard material, and magnetic spin wave resonance at middle frequency region. Microwave assisted magnetization reversals were also simulated assuming ECC nano-pillar with extremely high anisotropy field hard magnetic material. Essential ac field strength and microwave frequency for magnetization reversal were found to be less dependent on anisotropy field for the hard magnetic material, when magnetization reversal is induced by magnetic resonance for the soft magnetic material.
