摘要：

Magnetic Fe3O4 nanoparticles (NPs) were successfully synthesized by the one-step reduction method. The microstructure, morphology, and magnetic properties were characterized by XRD, SEM, TEM, and vibrating sample magnetometer. Characterization results confirmed that the as-synthesized Fe3O4 NPs had high purity and nearly spherical shape with an average crystallite size varied from 44 nm to 65 nm. The synthesized Fe3O4 NPs exhibited excellent magnetic properties, including high saturation magnetization (M-s = 93 emu/g), low coercivity (H-c = 110 Oe) and remanence (M-r = 18.6 emu/g), and high magnetic response (5 s). Among that, the M-s 93 emu/g value of the synthesized Fe3O4 NPs is higher than other methods. The size how to effects on nanoparticles' magnetic performance were discussed in detail. Including the reason that H-c and M-r of the NPs fell off with increasing average grain size. These results provided a new platform for further study of highly magnetic Fe3O4 NPs. Graphical abstract
