Image of FIG. 1.
FIG. 1.

Schematic of the cross-sectional sample structure (top), and top-view SEM images of the sample surfaces (bottom).

Image of FIG. 2.
FIG. 2.

Field-dependent magnetization normalized by the saturation magnetization ( ) for the three samples as measured with VSM, with field applied perpendicular (dashed lines), and parallel (solid lines) to the sample surface. Solid symbols correspond to the integrated in-plane magnetization profiles as measured with PNR.

Image of FIG. 3.
FIG. 3.

Measured PNR spectra (symbols) at 0.82 T for the A = 3.2 (top), A = 1.6 (middle), and A = 0.7 (bottom) samples. Solid and dashed lines are fits to the data. Note the different vertical scales for the three panels. Error bars correspond to , and are smaller than the point size for much of the data shown.

Image of FIG. 4.
FIG. 4.

Nuclear (solid, left axis) and magnetic (dashed, right axis) depth profiles for the (a) A = 3.2, (b) A = 1.6, and (c) A = 0.7 samples.

Image of FIG. 5.
FIG. 5.

Nuclear (solid, left axis) and magnetic (dashed, right axis) depth profiles, and corresponding cross-sectional TEM images for (a) A = 3.2, (b)A = 1.6, and (c) A = 0.7 samples. The scale of the TEM images matches that of the depth PNR profiles. For each sample, the surface Co/Pt multilayer is delineated by a vertical bar.

Image of FIG. 6.
FIG. 6.

Aspect ratio dependencies of (a) CoPt surface coverage, (b) relative pore circumference, (c) total surface near-saturation magnetization, and (d) normalized surface near-saturation magnetization. Solid lines are guides to the eye. Error bars correspond to .

Image of FIG. 7.
FIG. 7.

(a) Field-dependence of the normalized surface Co/Pt magnetization as determined from PNR (open symbols). (b) Comparison of surface and sub-surface Co/Pt magnetizations for the A = 0.7 sample. Error bars correspond to . Lines are guides to the eye.
