摘要：

In order to improve the absorbing properties of M-type barium ferrite absorbing materials, M-type barium ferrite/graphene oxide composites with different graphene oxide contents were synthesized by the sol-gel auto-combustion method. X-ray diffraction (XRD), a scanning electronic microscopy (SEM), a physical properties measurement system (PPMS-9), and a vector network analyzer were used to analyze their structure, surface morphology, magnetic and absorbing properties, respectively. The results show that the absorbing band of the composite absorbing material is widened and the absorbing strength is increased compared with the pure M-type barium ferrite. The sample with the content of doped graphene oxide of 3% has the minimum reflectivity at 10 to 18 GHz frequencies. Hence, the doped graphene oxide effectively improves the absorbing properties of M-type barium ferrite. © 2015, Editorial Department of Journal of Southeast University. All right reserved.
