摘要：
The Hall resistivity and magnetization of high quality asymmetric La0.7Sr0.3MnO3/SrTiO3/SrRuO3 and La0.7Sr0.3MnO3/BaTiO3/SrRuO3 superlattices were investigated. The Hall resistivity hysteresis curves have a complex magnetic field dependence in an intermediate temperature regime that is not reflected in the global magnetization. We interpret this as arising either from the formation of complex magnetization textures that lead to the appearance of a topological Hall effect or from the shift of the Weyl nodes in SrRuO3 by the coupling to the adjacent La0.7Sr0.3MnO3 magnetization.
