FIG. 1.

Evolution of (a) the exchange bias field and (b) the coercivity with the maximum in-plane field after applying along the stripes (full symbols) and the continuous film (empty symbols). Also shown are a SEM image showing a detail of the array of stripes (upper inset), and hysteresis loops for both the stripes and the continuous film (bottom inset).

FIG. 2.

MFM images at remanence after applying for (a) continuous film and (b) stripes ( applied along them).

Image of FIG. 3.
FIG. 3.

(a) In-plane hysteresis loops for the stripes (full symbols) and the dots (empty symbols) with both and applied perpendicular to the stripes. MFM images at remanence after applying along the direction indicated by the white arrows for (b) stripes and (c) dots.

Image of FIG. 4.
FIG. 4.

Two-dimensional magnetic configurations simulated for a stripe [(a), and (b)] and for a square dot, (c) when following a complete in-plane hysteresis loop with the field sequence along the axis (a) and axis, [(b) and (c)]. Blue and red indicate positive and negative out-of-plane magnetization, respectively. The magnetic configurations of the NiFe layer and all the bilayers are shown for . Only the NiFe layer and the top PtCo layer are illustrated for all other fields.
