Abstract

We have investigated the magnetic properties of highly coercive FePt films prepared on both MgO (001) and MgO (110) substrates with various film thicknesses (t_N). FePt (001) films with perpendicular magnetization and FePt (101) films with a canted easy magnetization axis (c-axis) were prepared on MgO (001) and MgO (110) substrates, respectively. At the critical thickness, where the film morphology changes from a particulate to a continuous state, a drastic decrease in the coercivity H_c has been observed for the FePt (001) film, while no jump of H_c has been observed for the FePt (101) films.
