FIG. 2.

FORCs (insets) and FORC diagrams of Co NW and NT ordered hexagonal arrays with different diameters and lattice parameter of , when applying the magnetic field parallel to the wire/tube long axis.

Image of FIG. 3.
FIG. 3.

Magnetic interactions, extracted from the FORC diagrams in Fig. 2 , as a function of the wire/tube diameter. Inset shows the cross-section of the FORC diagram along the Hu axis for NW and NT arrays with .

FIG. 4.

Coercive field along the parallel direction, extracted from the maximum value of the FORC diagrams ( ) in Fig. 2 , and from the major magnetic hysteresis loops ( ), as a function of the NWs/NTs diameter.

Image of FIG. 5.
FIG. 5.

Magnetic hysteresis loops of ordered Co NW (left) and NT (right) arrays with and , measured at different angles of H, in steps. Inset shows the angular dependence of squareness (dots—experimental data and line—theoretical calculations).

Image of FIG. 6.
FIG. 6.

Angular dependence of the coercive field measured experimentally (dots) and calculated analytically (C mode: black solid; T mode: green dashed; and V mode: orange dotted) for Co NW and NT arrays in NpATs with different outer diameters.
