One major challenge in engineering the magnetism of oxide heterostructures is controlling orbital reconstruction by tuning the charge transfer effect. This paper investigates the forward and backward charge transfer effect and the induced magnetic properties of BiFe 1− x Mn x O 3 /La 2/3 Ca 1/3 MnO 3 heterostructures. Interfacial ferromagnetism is found to be qualitatively tunable by tuning the spatial distribution of interfacial electronic states. The subtle balance of magnetic coupling between FeOMn and MnOMn changed as the electronic structures are modified by charge transfer. The ions' valence is strongly correlated with the interfacial magnetic properties, extending the concept of the charge degrees of freedom affecting the magnetic coupling properties.
