A sheet film with layer sequence Si/Ta/Pt/Ir20Mn80/Co/Ru/Co/FeOx/Co/Cu/Co/ Ni80Fe20/Ta was grown to fabricate the devices. Magnetization, magneto-transport, angle-dependent resistance, and Fe L3,2-edge X-ray absorption spectroscopy were performed on the sheet film and microfabricated devices. The sheet film and devices had in-plane orthogonal interlayer coupling between the Co layers across the NOL. The sensing capability of the devices was tested and it appears that the NOL affect
