Ferromagnetic heterostructures with strong interfacial Dzyaloshinskii-Moriya interaction (DMI) have been extensively studied, because they can host topologically non-trivial spin textures, such as skyrmions. The topological magnetic structures stabilized by interfacial DMI can be probed by the occurrence of the topological Hall effect (THE) in an experimental setup in which the anomalous Hall effect (AHE) can be simultaneously measured with the magneto-optic Kerr effect (MOKE). Here, we focus on the study of the AHE and MOKE of epitaxial heterostructures composed of ferromagnetic SrRuO3 and large spin-orbit coupling perovskite oxides, such as SrIrO3. We aim to elucidate the origins of the anomalies of the Hall resistivity exhibited by these heterostructures, as they have been previously assigned to the formation of skyrmions.
