Figures

Image of FIG. 1.
FIG. 1.

(a) Schematic of the fabrication process for the antidot magnetic film. (b) Cross-sectional view of block copolymer templated organosilicate on top of a PMGI underlayer after removal of the polystyrene and unprotected PMGI with an oxygen reactive ion etch. (c) Scanning electron micrograph of antidot array 1. (d) Scanning electron micrograph of antidot array 2.

Image of FIG. 2.
FIG. 2.

(a) Measured hysteresis loops of single-layer Co antidot arrays. (b) Half hysteresis loops of single-layer Co arrays based on micromagnetic modeling. [(c)–(f)] Magnetic configuration calculated for single-layer Co antidot arrays: (c) array 1 at reverse field, (d) array 1 at , (e) array 2 at , and (f) array 2 at . The reverse field was applied from right to left. The red (lighter shade) color indicates the original left-to-right magnetization direction and blue (darker shade) indicates the reversed regions. Arrows show the magnetization directions of some of the cells.

Image of FIG. 3.
FIG. 3.

Major and minor hysteresis loops of the multilayers measured for (a) continuous film, (b) array 1, and (c) array 2. (d) A schematic representation of the four possible magnetic configurations for the Co and NiFe layers.

Image of FIG. 4.
FIG. 4.

Magnetoresistance data for (a) continuous film, (b) array 1, and (c) array 2.

Image of FIG. 5.
FIG. 5.

[(a)–(e)] Snapshots of domain structures and (f) half hysteresis loop of the multilayers based on results of simulations at a field of (a) (b) , and (c) for array 1 and (d) and (e) for array 2, after positive saturation. The Co and NiFe layers have been separated for clarity. The reverse field was applied from right to left. Color scheme as in Fig. 2.

Tables
