摘要
The experiments on the [t1Pt/0.4Co]5/(0.2–5.0)Ru/[0.4Co/t2Pt]5 (thickness unit is nm) multilayers with perpendicular anisotropy (PA) indicate that the interlayer coupling shows an antiferromagnetic (AF) and a ferromagnetic oscillatory behavior with the thickness of Ru spacer layers from 0 to 5.0 nm, and that the AF oscillations display a superposition of two different periods, which are 0.8 and 1.1 nm, respectively. Moreover, we found that the magnitude of AF coupling strength J is closely related to the magnitude of PA caused by varied thickness of nonmagnetic Pt layer. Our experimental results can be explained by Bruno’s electron-optics model.
