  • Title: High coercivity of ordered macroporous FePt films synthesized via colloidal templates.
    Author: Iskandar F, Iwaki T, Toda T, Okuyama K.
    Journal: Nano Lett; 2005 Jul; 5(7):1525-8. PubMed ID: 16178269.
    Abstract:
    The preparation of a three-dimensionally (3D) ordered macroporous iron-platinum (FePt) film derived from monodisperse FePt nanoparticles (approximately 3 nm in diameter) and polystyrene latex particles (254 nm in diameter) is described. The prepared film has a hexagonally ordered porous structure and coercivity up to 10 kOe after annealing at a temperature of 600 degrees C. We also found that size of FePt particles was maintained at around 3 nm, even after annealing at a temperature of 600 degrees C.
