FIG. 1.

(Color online) (a) Three-dimensional AFM image of the BMAL structure. Inset shows the line profile. The hard and easy axes and the anti-dot positions are indicated. Note the terms “nearest neighbour” and “next nearest neighbour.” (b) Cross-sectional FESEM images of the BMAL structure (upper) and a top view with lattice parameters (lower).

FIG. 2.

(Color online) Hysteresis loop of the longitudinal Kerr rotation taken along the magnetic easy axis of the lattice plane and the corresponding field-dependent MFM images at (a) −400, (b) −100, (c) 0, (d) 100, (e) 125 [arrows shows shifting of demarcation line and not magnetization vector], and (f) 400 Oe. The arrows indicate the magnetization vector, demarcation lines, and anti-dot position in the MFM images.

FIG. 3. (Color online) Hysteresis loop of the longitudinal Kerr rotation taken along the magnetic hard axis of the lattice plane and the corresponding field-dependent MFM images at (a) −400, (b) −200, (c) 0, (d) 50, and (e) 200 Oe. The arrows indicate the magnetization vector, square frames showing chain reversals, and anti-dot position in the MFM images.

FIG. 4.

(a) Representative MOKE hysteresis curves taken along different lattice directions of the BMAL sample: EA—easy axis (0°), SEA—semi-easy axis (30°), and HA—hard axis (90°). Angular dependence of squareness (Mr/Ms ) and coercivity (Hc ) for (b) the BMAL system and (c) the single-layer Co-MAL system.
