Image of FIG. 1.
FIG. 1.

(Color online) Simulated spin configurations for perfect ring with (a) concave left (top)/concave right (bottom) magnetization structure and (b) concave right (top)/concave right (bottom) magnetization structure. (c) Designed ring with triangular fins for the nucleation of concave left (top)/concave right (bottom) magnetization structure. (d) Designed ring with triangular fins for the nucleation of concave right (top)/concave right (bottom) magnetization structure. The number of unit cells is reduced in each ring for display purpose. The gray scale represents the magnetic pole density distribution.

FIG. 2.

(Color online) SEM images of the permalloy rings with triangular fins at (a) θ = 15°, (b) θ = 30°, (c) θ = 45°, and (d) θ = 60° with respect to the field (H) direction. The arrows indicate the sweeping directions of field H in MR measurement. (Left-handed figures): the triangular fins are at diagonal sides with respect to the field direction. (Right-handed figures): the triangular fins are at the same side with respect to the field direction. The dotted circles represent the triangular fins. Each ring is 8 μm, 6 μm, 1 μm, and 30 nm for outer diameter, inner diameter, linewidth, and thickness, respectively, and the length of each fin in radial direction is 0.4 μm. The included angle of the fin structure is 60°. The inset in Fig. 2(a) represents the enlargement of the fin.

FIG. 3.

(Color online) Experimentally obtained MR curves of permalloy rings with triangular fins (θ = 15°) at the same side (a) and at diagonal sides (b) with respect to the field direction. The insets indicate the magnetization states in the sweep-up process.

Image of FIG. 4.
FIG. 4.

(Color online) Experimentally obtained MR curves of permalloy rings with triangular fins (θ = 30°) at the same side (a) and at diagonal sides (b) with respect to the field direction. The insets indicate the magnetization states in the sweep-up process.

Image of FIG. 5.
FIG. 5.

(Color online) Selected MR curves of permalloy rings with triangular fins (θ = 45°) (a) at the same side and (b) at diagonal sides with respect to the field direction.

Image of FIG. 6.
FIG. 6.

(Color online) Selected MR curves of permalloy rings with triangular fins (θ = 60°) (a) at the same side and (b) at diagonal sides with respect to the field direction.
