In this context, identifying interfaces that exhibit orbital–momentum locking and an orbital Rashba–Edelstein response to an external electric field is of primary importance. In this work, we experimentally investigate the Co|Al system and extend the study to Co|Pt|Al structures. We show that inserting ultrathin Pt layers between Co and Al can significantly modify the orbital properties, highlighting the critical role of Co|Al orbital bonding in generating orbital polarization. We further model the orbital response of these systems using semi-phenomenological approaches and linear-response theory within the framework of density-functional theory.
