La-doped Sr-hexaferrite (Sr1−x La x Fe12O19) (x = 0.05, 0.10, 0.15, 0.20) nanopowders with particle size ranging from 80 to 110 nm were successfully synthesized by sol–gel auto-combustion. The phase formation temperature increases, while the particle size decreases as the La-doping content goes up. The partial substitution of Sr2+ by La3+ results in the suppression effects on the growth-up of the crystallites and the enhancement of the electron hopping between Fe3+ with different valences, which leads to the improvement in the dielectric loss and magnetic loss. Therefore, both the microwave absorbing abilities and absorbing frequency ranges are tuned by La-doping. The synthesized Sr-hexaferrite nanopowders with doping element content of 0.10 demonstrate the fine broad microwave absorbing properties.
