Electronic Inhomogeneity Influence on the Anomalous Hall Resistivity Loops of SrRuO₃ Epitaxially Interfaced with 5d Perovskites.

ABSTRACT: SrRuO₃, a 4d ferromagnet with multiple Weyl nodes at the Fermi level, offers a rich playground to design epitaxial heterostructures and superlattices with fascinating magnetic and magnetotransport properties. Interfacing ultrathin SrRuO₃ layers with large spin-orbit coupling 5d transition-metal oxides, such as SrIrO₃, results in pronounced peaklike anomalies in the magnetic field dependence of the Hall resistivity. Such anomalies have been attributed either to the formation of Néel-type skyrmions or to modifications of the Berry curvature of the topologically nontrivial conduction bands near the Fermi level of SrRuO₃. Here, epitaxial multilayers based on SrRuO₃ interfaced with 5d perovskite oxides, such as SrIrO₃ and SrHfO
