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.
描述了一种由单分散的FePt纳米颗粒（直径约3纳米）和聚苯乙烯胶乳颗粒（直径254纳米）制备的三维（3D）有序大孔铁铂（FePt）薄膜。制备的薄膜具有六方有序的多孔结构，在600摄氏度退火后矫顽力高达10 kOe。我们还发现，即使在600摄氏度退火后，FePt颗粒的尺寸仍保持在约3纳米左右。
