【 摘 要 】

In the last years, magnetite (Fe3O4) nanoparticles have been prepared with various methods to produce the Fe3O4with high performance especially in microwave absorption properties. In general, the characterization of reflection loss using microwave of the Fe3O4particles has been carried out in the range of 2-18 GHz. In this work, the rotational molecular model was developed to analyze the reflection loss peaks in the range of the frequency. The primary technique of simulation was an interpolation of peak frequencies originating from the molecular rotational transition of the Fe3O4particles. The data analysis presented that the mechanism occurs at the electromagnetic absorption of the Fe3O4particles is rotational molecular. Interestingly, it is presented that the result of the simulation is in line with the results of the characterizations of several materials that have been reported in some literature.
