The strongly correlated of multi-degrees of freedoms at transition metal oxide heterointerfaces greatly enriches its physical properties and expands the relevant application fields. It has been reported that dimensionality is an effective method to tune the properties of oxide heterostructure. SCO films display structural transformation from planar-type to chain-type with the change of thickness. In this text, the high quality of SCO/LCMO superlattices are deposited by pulsed laser deposition system. And the interfacial exchange coupling effect is effectively manipulated by controlling the dimensionality of SCO layer. Combined with XAS measurement, it is found that the charge transfer would occur at heterointerface. When the SCO layer is thin, the interfacial superexchange coupling supported by charge transfer generates a weak magnetic moment to pin the ferromagnetic LCMO layer. The charge transfer would decrease as the SCO layer is thicken. Meanwhile, the long-range antiferromagnetic order in thicken SCO layer can interacted with LCMO layer and resulted in the exchange bias effect. This experiment confirms the important role of dimensionality to tune properties in multifunctional oxide heterostructure.
