摘要
A liquid-assisted one-step sintering method was proposed for the synthesis of L1(0)-FePt superfine nanoparticles. The liquid assisted Fe and Pt precursors were homogeneously deposited on NaCl media, which facilitated the nucleation rates, obviously reduced the particle size and promoted the orderly transformation. Through optimizing the sintering parameters, superfine L1(0)-FePt nanoparticles (about 7 nm, TEM) with coercivity as high as 2.29 T were obtained. This research highlights the feasibility of synthesizing L1(0)-FePt nanoparticles with superfine sizes and ultra-high coercivity.
