Micromagnetic study of magnetic printing onto various slave media

In this paper, the micromagnetic analysis of magnetic printing onto various slave media, such as the coupled granular-continuous media (CGC) and exchange coupled composite media (ECC) was carried out. In the single-layered granular medium, the magnetization patterns are printed on the slave medium corresponding to the master patterns, but defects appear in the center of the magnetization pattern in this case. On the other hand, in the CGC and ECC media, there is no defect in the center of the magnetization patterns due to the effect of a capping layer. The bit squareness in ECC medium is superior to those of the other media. It is clarified that the magnetic printing can be applied onto various media.
