초록

We prepared CoCr thin film for perpendicular magnetic recording media by facing targets sputtering system(FTS system) which can deposit a high quality thin films in plasma-free state and wide range of working pressure. In this study, we investigated that the effect of sputtering condition , that Argon gas pressure and substrate temperature, on magnetic and crystallographic characteristic of CoCr thin film as well as the variation perpendicular coercivity in changing of film's thickness. Crystallographic and magnetic characteristic of prepared thin films were evaluated by x-ray fractometry(XRD), vibrating sample magnetometer(VSM) and kerr hysteresis loop measurement.
