摘　　要：fct结构的FePt纳米材料以其较高的矫顽力和单轴磁晶各向异性等优异性质而受到广泛的关注。本文首先介绍了FePt纳米材料的结构性质和退火导致的团聚现象,然后概述了近年来国内外FePt纳米材料的制备及应用进展,包括化学和物理方法制备的FePt纳米材料及其在磁记录、永磁体等多方面的潜在应用。The nanostructured FePt alloy materials have attracted considerable attention due to its excellent intrinsic properties, i.e. high coercivity （He） and large uniaxial magnetocrystalline anisotropy. This work first introduces the structures and properties of FePt nanomaterials, as well as annealing-induced aggregation effect. It further reviews recent advancements in fabrications of FePt nanomaterials by physical or chemical synthesis, and potential applications are also presented mainly in permanent magnetism and ultra high density data-storage, etc.
