| description | This paper demonstrates the results of the detailed studying of the magnetic behavior of Co2FeAl alloy nanoparticles synthesized through a co-precipitation method. First order reversal curves (FORCs) diagrams were used consequently. The obtained results showed that the prepared alloys consist of a mixture of the low-coercivity grains (Hc ~ 0), and interacting single-domain high-coercivity grains. Elongated FORC diagrams along Hc axis indicated a wide particle size distribution in the products. Spherical and uniform nanoparticles with a size distribution of 30-90nm were observed in the SEM and TEM images of the synthesized samples. Maximum values of Ms (about 91.5 emu/g), and coercivity (487 Oe) were obtained for the sample synthesized with the optimum annealing conditions up to 700 ̊C with 10 ̊C/min. |
