ABSTRACT:
Disclosed herein are Ba-containing plate like magnetoplumbite type ferrite particles for magnetic recording having the composition of AO.n{(Fe.sub.1-X M.sub.X).sub.2 O.sub.3 } (wherein A represents Ba or Ba and Sr, M represents Zn and Ti, or Zn, Co and Ti, n=6.5-11.0, and x=0.05-0.25) and the change of coercive force of said particles at a temperature of 20.degree.-120.degree. C. in the range of -2.0 Oe/.degree.C. to +2.0 Oe/.degree.C., and magnetic recording media using the same.
