Paper Title:
Analysis of the Magnetic Anisotropy in Ba Ferrite Particles
  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.
