Abstract
The magnetic anisotropy of Co/Ti-doped Ba ferrite particles for application in recording
media is studied. A method which deduces the anisotropy from the measurement of the reduced
perpendicular magnetization and allows to find also the distribution of anisotropy fields is
employed. The effect of the doping ions content, of the alignment degree of the particles and of the
variation of the temperature on the anisotropy is analysed and discussed, taking account of the
contemporary presence of magnetocrystalline and shape anisotropy, with different easy
magnetization axes, in the Ba ferrite particles.
