New concept of material design for CoPtCr-SiO2 based ECC media ¢?? Application of hcp disordered Co-Ir alloy with negative Kugrain to the soft-mag part ¢??..
In this paper, we introduce the unique newly material, the hcp disordered Co-Ir alloy with negative uniaxial magnetic anisotropy, and propose a new concept of the ECC media using this new CoIr-SiO2 granular film instead of conventional soft layer material. In real magnetic writing, negative-Ku grain part plays a role of SUL function. Co-Ir alloys with negative-Ku grain shows soft magnetism in the c-plane due to the high crystallographic symmetry. Within the frame work of this presentation, simulation of magnetization reversal by LLG equation for this stacked media will be also discussed.
