摘要：
The structure and magnetic properties of Fe-Pt/Fe films have been investigated to confirm exchange coupling behavior. Intermediated layer of Cu was inserted between FePt layer and Fe layer. It was found that the switching field (Hsw) was decreased with decreasing the thickness of Cu layer, indicating that the distance of the exchange coupling between FePt layer and Fe layer was less than 1 nm. The magnetic properties of FePt/Fe films were remarkably changed by the thickness of each layer. With increasing the thickness of Fe layer, the saturation magnetization (Ms) increased but the coercivity (Hc) decreased. From the magnetic force microscope observation, it was revealed that a remarkable difference was exist between FePt thin film and FePt/Fe thin film. © 2010 The Institute of Electrical Engineers of Japan.
