摘要
Co-alloy/Cr thin-film longitudinal magnetic recording media were prepared by de magnetron sputtering onto circumferentially textured NiP/Al substrates at various deposition conditions. The: in-plane crystallographic structure was analyzed by grazing incidence X-my diffraction using synchrotron radiation. The coercivity is found to depend on both preferential c-axis alignment and compressive strain. In-plane anisotropy of coercivity increases with increasing ill-plane anisotropy of both c-axis alignment and compressive strain. The degrees of these in-plane crystallographic anisotropies depend on the substrate temperature and substrate bias voltage.
