AbstractUltrathin SrFe12O19 nanosheets were successfully synthesized by modified hydrothermal method. The structure, morphology and properties were characterized and investigated by using X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), Vibrating sample magnetometer (VSM) and Vector network analyzer (VNA). The results revealed that the temperature and diethylene glycol were responsible for ultrathin structure and good dispersity of SrFe12O19 nanosheets. The SrM nanosheets showed strong magnetocrystaline anisotropy and large coercive force, which enhanced microwave absorbing properties of SrFe12O19. The reflection loss (RL) of a composite absorber with thickness of 3.5 mm reached a maximum value of -28.6 dB and the effective absorption bandwidth (RL < -10 dB) was 0.92 GHz at the high frequency region, exhibiting excellent microwave absorbing properties as promising microwave absorber.
