Abstract :
FePt films are prepared by RF sputtering at intermediate temperatures (up to 550°C) followed by thermal annealing at the same temperature. Structural characterization is then performed by means of X-ray diffraction and transmission electron microscopy. The results indicate that the effect of in-situ annealing after the high-temperature growth turns out to be essential in obtaining well-oriented and highly coercive films. The magnetic properties are studied at room temperature by an alternating gradient force magnetometer.
