| Abstract: | Pr-doped Ba ferrite composite film was prepared by a sol-gel method and an in situ polymerization method, respectively. The structure, morphologies, magnetic properties and microwave absorption properties of the samples were characterized using X-ray diffractometer (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscope(SEM), vibrating sample magnetometer (VSM) and magnetic vector network analyzer. The results show that the saturation agnetization (Ms) and the remanent magnetization (Mr) of the composite film are lower than that of Ba Ferrite film, but the coercivity force (Hc) of the composite film is higher than that of Ba Ferrite film. Pr doped Ba ferrite/ polypyrrole composite film has both dielectric loss and magnetic loss, which is beneficial to widen microwave band and improve microwave absorption properties. |
