Energy barriers of elongated Fe nanoribbons as a function of their width at zero applied field for two different orientations of the anisotropy axes with respect to the stripe long axis.

Plane view of (a) the minimum and (b) the saddle point configurations for nanostripe with width, Fe easy axis at 45° to the long stripe axis and zero applied field.

FIG. 3.

Plane view of (a) the minimum and (b) the saddle point configurations for nanostripe with width, Fe easy axes at 45° to the long stripe axis and zero applied field.

FIG. 4.

Energy barriers in Fe nanoribbons as a function of applied field for nanostripes with Fe easy axes at 45° to the long stripe axis and different widths of the stripe. The solid line corresponds to typical magnetometer measurements. The inset shows the system energy versus the constraint parameter for a nanostripe with width and for several applied field values.

Comparison of the coercivity values obtained through static micromagnetic simulations with those obtained via energy barriers evaluation at and measurement time .
