Harnessing orbital currents in solid-state systems shows promise for the development of next-generation information technologies. Recently, orbital pumping has attracted considerable attention as a mechanism for orbital-to-charge conversion in materials with weak spin–orbit coupling. The efficiency of this process has been shown to strongly depend on the electronic structure of the ferromagnetic layer [3]. In this study, we investigate orbital current generation in Fe/MgO heterostructures by modifying the interfacial electronic structure. Specially, the correlation between the interfacial electronic states and the orbital current generation in the Fe/MgO system will be discussed.
