| 520 | _ | _ | |a Topological magnetic textures, known as magnetic skyrmions, hold significant promise for applicationsas nanoscale information components in logic and memory devices. These quasiparticles,characterized by their swirling spin configurations, exhibit unique advantages due to their stability,diminutive size, and the low current densities required for manipulation [1]. In transition metal oxides,electronic correlations between 4d and 5d oxides in bilayer forms induce strong spin-orbit coupling(SOC), facilitating the formation of magnetic skyrmions on the surface of SrRuO3 (SRO). Stacksof SrRuO3/SrIrO3 (SIO) epitaxial layers integrate essential elements such as the Dzyaloshinskii-Moriya interaction (DMI), large perpendicular magnetic anisotropy (PMA), and spin-orbit torques(SOT) to stabilize magnetic skyrmions and enable their efficient current-driven motion. Bilayers ofSRO/SIO are grown on TiO2 terminated SrTiO3 (STO) (001) substrates, where the growth of SRO isachieved via High Oxygen Pressure Sputtering (HOPS) and SIO via Molecular Beam Epitaxy (MBE).Precise control of film thickness is crucial to maintain the intrinsic properties of both materials andobserve magnetic skyrmions. Therefore, we systematically vary the thickness of both the layers tooptimize their magnetic properties, magnetoresistance and the Hall effect that includes ordinary Halleffect (OHE), anomalous Hall effect (AHE), and Topological Hall effect (THE). Given the challengesassociated with directly observing skyrmions directly at the nano-meter scale in the real space, weemploy the topological Hall effect as an indirect method to characterize magnetic skyrmions in ferromagneticthin films[2]. For detailed interfacial and surface studies of the thin films, PolarizedNeutron Reflectometry (PNR) and Grazing Incidence Small Angle Neutron Scattering (GISANS) willbe performed. The expected results will test the hypothesis of the presence of ordered magneticskyrmions and their contribution to the topological Hall effect in the bilayer oxide thin film, potentiallyadvancing our understanding of skyrmion dynamics and their application in spintronicsdevices.[1] N.
