The hysteresis loops of CGC and ECC media is used to investigate the effect of thickness.
The thickness of CGC and ECC layer thickness is varied from 0 nm to 7.5 nm with step size of 2.5 nm
The increasing slope of CGC medium and the reduction of Hc are found with increasing of continuous thickness.
For ECC medium, the effect of coupled layer thickness only results in the decrease of Hc.
