Scheme representing the parameters used in the characterization of exchange-bias systems. The arrows indicate the directions of the magnetic field sweeps.
Remanence curves for the Co/IrMn film, where was attained by dc demagnetization; dashed lines: the respective SFDs. The solid lines are guides to the eyes.
(left) and Henkel (right) plots for the Co/IrMn film obtained after dc demagnetization performed before obtaining . The solid ones are guides to the eyes and the dashed lines correspond to the unbiased non-interacting uniaxial anisotropy case.
Left: representative experimental Henkel plots for the Co single layer and for the films obtained after dc demagnetization. Right: Plots simulated for different percentages of the FM/AF contact area(using as parameters , , and as a mean value with respective . The inset shows plots simulated as the one with 100% FM/AF contact area for three different (in radians). The dashed lines correspond to the non-interacting case and the solid lines are guides to the eyes.
(a) The here-defined and plots for the FM/AF film ( ) and (b) as a function of for the Co/Cu/IrMn series. The solid lines are guides to the eyes.
