(Color online) Experimental set of FORCs of a CoFeB nanowire array (nominal , ), measured perpendicular to the nanowire axis (, ). For practical reasons, only one-eighth of the measured curves is shown. Some additional points with are added in order to obtain an extended FORC diagram. The inset presents a zoom on to show the upper branch of the MHL (dashed), along with the initial slope of the FORC (solid).
(Color online) FORC diagram calculated with the curves in Fig. 1 (irreversible processes only). Negative regions are represented in dark and without border.
(Color online) Percentage of reversible reversal occurring at of a CoFeB nanowire array, obtained with the curves in Fig. 1.
(Color online) Comparison of the areas contained between and from FORC diagrams calculated with the curves in Fig. 1 and with different methods. (a) Extended FORC, (b) without additional points, (c) extrapolated FORC, and (d) the same sample but measured with smaller parameters (, , and ). The scale is normalized to fit (c), while higher and smaller values appear, respectively, in white and black.
