Temperature Study of the Antiferromagnetic Coupling at the Interface of La0.7Sr0.3MnO3 and SrRuO3 Bilayers

We have studied the antiferromagnetic coupling at the interface of the La0.7Sr0.3MnO3/SrRuO3 bilayer as function of temperature. We measured the La0.7Sr0.3MnO3 magnetization reversal while the SrRuO3 magnetization is blocked due to a field cooled procedure and because of its high coercive field. Eve...

Zusammenfassung:We have studied the antiferromagnetic coupling at the interface of the La0.7Sr0.3MnO3/SrRuO3 bilayer as function of temperature. We measured the La0.7Sr0.3MnO3 magnetization reversal while the SrRuO3 magnetization is blocked due to a field cooled procedure and because of its high coercive field. Even if in this system, the La0.7Sr0.3MnO3 magnetization cycle may be explained by two exchange couplings which coexist up to 120 K, the exchange bias and the coercive field from 5 K to 300 K have a similar behavior from some ferromagnetic/antiferromagnetic...
