FIG. 1.

Structure and magnetic properties of F/S/F trilayer. (a) cross-sectional SEM image of the FIB-cut via down to the bottom Py layer with the inset showing the schematic of the F/S/F structure consisting of outer Py layers encapsulating the film; (b) SEM image taken from the top of the FIB-etched via showing the bottom terrace (surface of bottom Py layer) as well as couple terraces in the top Py layer; (c) MFM image of the area in (b) showing alignment of top and bottom magnetic stripe domains.

FIG. 2.

Normalized resistivity of the MoGe bridge sandwiched between Py layers with different thicknesses—(a) 200 nm, (b) 600 nm, and (c) 1500 nm. The orientation of the stripe domains with respect to the current (parallel or perpendicular) is indicated in the legend. The applied magnetic field is directed normal to the plane of the film. Shaded areas show the temperature range where the conductance anisotropy exceeds an order of magnitude in zero external magnetic field.

FIG. 3.

diagrams of the 20 nm thick MoGe bridge sandwiched between Py layers with different thicknesses—(a) 200 nm, (b) 600 nm, and (c) 1500 nm for the two orientations of the stripe domains with respect to the supercurrent.
