Hysteresis loop of the (bottom)/Ag/ (top) PSV. The inset shows the XRD spectrum (the unlabelled sharp peaks are inherent of the MgO substrate).
AFM and MFM images recorded for (a) completely saturated hard and soft under an applied field of , (b) partial reversal in soft under an applied field of −2 kOe, (c) partial reversal in hard under an applied field of −4 kOe, (d) −6 kOe, and (e) close to complete saturation of hard under an applied field of −8 kOe.
Minor hysteresis loops of the (bottom)/Ag/ (top) PSV recorded under the influence of the different magnetization state of the bottom , created through applied field of (a) 0, (b) −4 kOe, and (c) −20 kOe. The dotted line indicates the center of the minor hysteresis loop; the arrow indicates the direction of the shift in the minor hysteresis loop. Insets indicate schematically the influence of bottom on the reversal of top as described in the text.
Exchange bias field and coercive field of the soft layer vs applied field.
