Proximity induced magnetism and the enhancement of damping in ferromagnetic/heavy metal systems [dataset]

The relationship between proximity induced magnetism (PIM) at the heavymetal/ferromagnet interface and spin-transport across such interfaces has generatedsignificant debate. Element specific X-ray magnetic circular dichroism and ferromagneticresonance measurements were made on the same CoFe/Au/Pt and NiFe/Au/Pt thin filmsamples with varying Au thickness. An approximately linear relationship is observedbetween the magnitude of Pt PIM and magnitude of damping enhancement in bothsystems. The results demonstrate that electronic hybridization of the heavy metal andferromagnet is required for a full understanding of damping enhancement and interfacialspin-transport for spintronic devices
