摘要
We have studied the effect of "double" substitution in Ba0.7Sr0.3Fe12-2xCoxTixO19 on the structural and magnetic properties of M-type barium hexaferrite. The basic composition of Ba1-xSrxFe12O19 obtained by heat-treating carbonate-hydroxide precipitates has been optimized (x = 0.3). 2Fe(3+) -> Co2+ + Ti4+ substitutions considerably reduce the coercive force (H-c) and increase the magnetization (M-s) relative to Ba0.7Sr0.3Fe12O19.
