FIG. 1.

SEM image of the trilayer. White arrows indicate positions of edge dislocations in the hexagonal arrangement of the nanopores. The lower-right inset shows a higher magnification image of the antidot array.

FIG. 2.

Hysteresis loops at 5 and 300 K for planar (a) and perpendicular (b) measurements. The saturation magnetization for in-plane measurements is used to normalize the SQUID signals. (c) Cross-section schematics of the local morphology of the Co film.

FIG. 3.

(a) Temperature dependence of the coercive field (open symbols) and exchange field (full symbols), for in-plane (squares) and out-of-plane (circles) measurements. Lines are only guide to the eyes. (b) Field derivative of normalized magnetization deduced from the in-plane hysteresis loops measured at 5, 175, and 300 K. Open and full symbols are deduced from SQUID measurements along the ascending and descending branches of the hysteresis loops, respectively.
