FIG. 1.

(Color online) (a) Schematic structure of the polycrystalline Fe ring arrays. (b) Scanning electron microscopic images of the sample. A detailed image of one ring is shown on the bottom right corner.

FIG. 2.

(Color online) M-H hysteresis loops of (a) the 10 nm thick polycrystalline Fe ring arrays, (b) 30 nm thick polycrystalline Fe ring arrays, and (c) 50 nm thick polycrystalline Fe ring arrays; the first order derivative dM/dH of the loop’s descending branch (red) are plotted in the inset box located at the right bottom corner of each loop. (d) The remanence magnetization Mr, first step switching field Hc1, and second step switching field Hc2 as a function of the ring thickness tFe.

Image of FIG. 3.
FIG. 3.

(Color online) Selected MFM images showing the magnetic reversal process for (a) (1)–(5) the 10 nm thick polycrystalline Fe ring, (b) (6)–(10) the 30 nm thick polycrystalline Fe ring, and (c) (11)–(15)] the 50 nm thick polycrystalline Fe ring. All the MFM images were taken under the applied magnetic fields as marked at the top of the columns.

Image of FIG. 4.
FIG. 4.

(Color online) Micromagnetic simulated spin configurations of the 10 nm thick Fe ring in the magnetic reversal process (a)–(e), and the corresponding process for the 30 nm Fe ring (f)–(j) and 50 nm Fe ring (k)–(o). The magnetization direction is indicated by the color wheel or overlaid arrows.
