Figure 6.

In-plane field-dependent M(H) curves measured at T = 5 K, with the applied field perpendicular (solid square) and parallel (open circle) to the axial direction of the nanochains with the sizes of a 33 ± 3 nm, b 78 ± 5 nm, and c 120 ± 12 nm. The upper left inset of a shows the M (H) curve with the diamagnetic background of silicon substrate. The lower right inset shows the M(H) curve by subtracting the diamagnetic contribution from the substrate
