Abstract :
The mechanism of the softness of high saturation magnetic flux density (Bs) Fe-Co-Al-O films with a thin underlayer is studied. In order to investigate the origin, the structural analysis was carried out by X-ray diffraction (XRD) measurements and transmission electron microscope (TEM) observation in detail. Fe-Co-Al-O films were prepared by RF magnetron sputtering in an Ar gas atmosphere. The film was deposited in Si/SiO2 substrate at 20°C. Magnetization curves were measured by a vibrating sample magnetometer (VSM).
