摘要
Effect of magnetic field annealing on chemical ordering of FePt films has been investigated. It is found that the ordering rate in FePt films is enhanced by applying a magnetic field during postdeposition annealing. Measurements of the structure and magnetic properties of FePt films reveal that the disorder-order transformation starts at or below 450degreesC when the film is annealed in a magnetic field of 40 kOe. The possible reason for the enhancement in the ordering of FePt films by magnetic field annealing is discussed. (C) 2004 American Institute of Physics.
