The thickness dependent magnetic domain structures in FePt/MgO(100)L1_0 ordered alloy thin films are investigated by Magnetic Force Microscopy (MFM), for as-deposited and AC-demagnetized states.Truncated stripe domains and bubbles are observed for as-deposited states.However, very regular maze patterns, with a tendency of aligning along the [110] direction for thickness greater than 1000 A are observed for AC-demagnetized states.Unreversed domains with edges parallel to the [110] direction appeared in the remanent states for thickness greater than 1000 A.The preferential alignment of the domains along the [110] direction are attributed to the groove-like surface morphology running along the [110] direction as revealed by Atomic Force Microscopy(AFM).
