(Color online) (a) Hysteresis loop of exchange-biased IrMn/CoFe film measured by the MOMM system. The direction of the backward and forward branch reversal is denoted by the arrows. (b) The domain reversal patterns of IrMn/CoFe film for both forward and backward branches. The color code from red to blue represents the elapsed time from 0 to 6 s after the reversal field was applied. The measurements were carried out at ×500 magnification, corresponding to an observed area of 80 × 64 μm2. The direction of the applied magnetic field is indicates by the arrow.
(Color online) Probability distributions of the magnetization half-reversal time for both the forward and backward applied fields. The distributions were obtained from more than 100 repeated measurements of the magnetization reversal curves.
(Color online) The half-reversal time as a function of the applied magnetic field for the backward and forward applied fields. The red solid line represents the linear fit.
(Color online) (a) A series of six magnetization reversal patterns during backward branch reversal. (b) Distribution of the domain jump size in a log-log scale plot. The linear fit when is also shown as the red solid line.
