(Color online) Family of FORC’s (lines) and transverse hysteresis loops (open circles) measured at in the 0°, (b) 2°, (c) 8°, and (d) 45° orientations after field cooling in . The black dots in the FORC data mark the beginning of each reversal curve. The outer boundary of FORC’s traces out the longitudinal hysteresis loop.
(Color online) FORC distribution plotted as a function of local coercivity and bias field in the 0°, (b) 2°, (c) 8°, and (d) 45° geometries.
(Color online) (a) Normalized transverse hysteresis loop peak magnitude along decreasing and increasing field sweeps (open and filled triangles, respectively) and (b) the amount of irreversible switching obtained from FORC (squares) and the modified SW model (dashed line) in each geometry. Solid lines are guides to the eyes. The inset shows the measured (open circles) and simulated (lines) longitudinal hysteresis loop for . The irreversible portion of the magnetization switching calculated in the modified Stoner-Wohlfarth model is shown by the vertical bar.
