文摘

M-type CoAl doped BaSr hexaferrites synthesized by a ceramic method. Mossbauer studies agree with magnetic dilution depicted in hysteresis loops. Coercivity reduced from 266.0 Oe to 61.8 Oe in x = 0.0 to 1.0. Saturation Magnetization reduced from 64.0 to 39.4 emu/g in x = 0.0 to 1.0. Tunable Hc, Mr & Ha imply for possible recording & absorber applications.
