摘要
Plate-like ferrite particles with magnetoplumbite structure have a composition represented by the general formula of AO•nä(Fe1-(a+b)BiaMb)2O3ü wherein A is Ba, Sr or Ba-Sr; M is Zn-Nb, Zn-Ta or Zn-Sn; n is from 5.5 to 6.1; a is from 0.001 to 0.005; b is from 0.050 to 0.120; and the ratio of b/a is from 20 to 50. These particles are used in magnetic cards.
