Magnetism of FePt Nanoclusters in Polyimide

Figure 4

Hysteresis loops of KHN-FePt nanocomposite annealed at 460°C for 1 h, in an external magnetic field of 10,000 Oe. (a) Samples annealed in magnetic field perpendicular to the plane of the sample. (b) Samples annealed in magnetic field parallel to the plane of the sample.
