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 (tN). 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 Hc has been observed for the FePt (001) film, while no jump of Hc has been observed for the FePt (101) films.
