Schematic illustration of the field-dependent curvature of mixed state domains along the field direction which is directly related to σIMS used in the calculation of αorient. (a) For high values of Bapp the domains are large and the influence of the pins on the straightness along the field direction is limited. (b) For intermediate field values the mixed state domains are increasingly bent due to the interaction with the pinning landscape. This leads to an increase in σIMS and αorient with decreasing field. (c) For low fields approaching zero, the maximum curvature determined by the elastic moduli prohibits the accommodation of all pins, leading to an increased straightness and decreasing values of σIMS and αorient as compared with intermediate field values. The schematic drawings are exaggerated and not to scale. |
