With the rapid development of society, the demand for information storage is increasing. Hence, research involving magnetic storage materials is gaining importance. In this study, Fe3Mn3Co60.66Si33.34 powders were prepared via mechanical alloying and sintering. The effect of the sintering temperature on the crystal structure was analyzed by X-ray diffraction, and the results showed that doped Co2Si powder was successfully prepared. Vibrating sample magnetometry was used to investigate the magnetic properties of Fe3Mn3Co60.66Si33.34, and showed that the coercivity of the samples decreased with increasing sintering temperature. Fe3Mn3Co60.66Si33.34 sintered at 950 °C yielded a magnetic saturation strength of 36.42 emu/g, coercivity of 135.92 Oe, and remanent magnetization of 4.97 emu/g. Electron microscopy analyses showed that the prepared particles were spherical, and the average grain size increased with increasing sintering temperature. The electromagnetic loss was analyzed by simulating electromagnetic parameters, which revealed that the electromagnetic loss tangent decreased with increasing sintering temperature. Hence, it is inferred that Fe3Mn3Co60.66Si33.34 powder materials sintered at high temperatures are expected to have suitable properties for magnetic storage applications.
