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). 2Fe3+ → Co2+ + Ti4+ substitutions considerably reduce the coercive force (Hc) and increase the magnetization (Ms) relative to Ba0.7Sr0.3Fe12 O19.
