摘要：

The structural and magnetic properties of Fe-Pt nanoparticles with Fe2+/Pt4+ molar ratio of 1, 1.25, 1.5, 2 were studied in the as-prepared and annealed samples. The powders were produced by chemical reduction. The magnetization and coercivity of as-made particles were relatively low. After annealing, M-S increases and H-C decreases with increasing Fe2+/Pt4+ molar ratio. The maximum values of M-S and H-C obtained were about 75 emu/g and 20 kOe, respectively.
