摘要
We have investigated the exchange bias effect in La0.7Sr0.3MnO3/SrRuO3 bilayers that epitaxial grown in different directions and various substrates. A linear-tunable exchange bias effect, which related to the spin states of the SrRuO3 layers have been discovered. The spin state of Ru4+ play the centre role in the interaction, and proposes mechanisms to understand the Mn-O-Ru antiferromagnetic coupling. This study emphasizes the effect of the spin state as well as the exchange strength on the interfacial coupling, which may open a constructive approach in improving the performance of the related spintronic devices.
