“…In pure Ba ferrite particles the magnetocrystalline and shape anisotropy constants, respectively, are K 1 ¼ 3.3 Â 10 6 erg/cm 3 , K s ¼ 4.7 Â 10 5 erg/cm 3 , at room temperature. In the Co/Ti-doped particles we have analyzed the same constants, at room temperature, which are K 1 ¼ 4 Â 10 5 erg/cm 3 and K s ¼ 2.47 Â 10 5 erg/cm 3 [5,6]. The two anisotropies have comparable strength in doped particles.…”
