Abstract :
This work investigates the evolution of the magnetic anisotropy of Ba ferrite particles when cooled from room to low temperatures, studying both pure and Co/Ti-doped particles for magnetic recording media. Results show the magnetocrystalline anisotropy increases when the temperature decreases. The magnetic anisotropy feature of Co/Ti-doped Ba ferrite particles for magnetic recording is remarkably different at low with respect to room temperature, with appearance of multiple anisotropy axes.
