What is it about?
In this study, we investigate spin-to-charge conversion on a trilayer composed of Cobalt (Co), Antimony (Sb), and Permalloy (NiFe) using the spin-pumping (SP) technique. Our findings unequivocally demonstrate that the predominant process governing spin-to-charge conversion in the Sb layer is the Inverse Rashba-Edelstein effect (IREE), also, the SP signal remains near constant. This effect arises from the presence of surface states at both interfaces between the Co/Sb and Py/Sb layers. To provide context, we also present a comparison with the well-established spin-to-charge conversion observed in a Platinum (Pt) layer.

Why is it important?
Spin-to-charge conversion stands as a pivotal phenomenon in the rapidly advancing field of spintronics, poised to reshape modern technology. This study contributes to a deeper comprehension of spin-to-charge conversion driven by surface states within an Antimony film. The insights gained have the potential to inspire the development of novel, energy-efficient spintronics devices.
