Plate-like composite ferrite particles for magnetic recording and process for producing the same |
| abstract |
Plate-like composite ferrite particles for magnetic recording comprising plate-like composite ferrite Ba-containing particles which have a composition represented by 19 < (Fe + M)/Ba ≦ 22 calculated on the basis of the molar amounts of the elements Fe, M and Ba in the said particles as determined by fluorescence X-ray analysis and wherein M represents at least one metal (II) selected from Co, Ni, Zn, Mn and Mg and at least one metal (IV) selected from Ti, Sn, Zr and Ge, and in which there is a linear concentration gradient of Ba between the surface and the nucleation portion of the particles. |
