Stability of Bar Code Information Stored in Magnetic Nanowire Arrays

Figure 1

(a) Top view of the schematic representation of the inscription of information on magnetic bar codes inside a circular membrane of radius and height . Wires are perpendicular to the page penetrating it for the full length . Black areas represent wire magnetizations pointing up; white areas represent wire magnetization pointing down; gray areas indicate random orientation. An arbitrary bar code is shown in a rectangle of length and height . (b) Magnification of a possible background area presenting no magnetic order with total nil magnetization; (c) magnification of the bar code area showing ideal magnetization profiles producing bars with generic width , where runs over all bars.
