　　La-doped Sr-hexaferrite(Sr_1-xLa_xFe₁₂O₁₉)（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 Ladoping 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 elect...
