      abstract     = {Interfacial magnetism in complex oxide heterostructures
                      provides a powerful platform to uncover emergent phenomena
                      driven by strain, spin-orbit coupling (SOC), and broken
                      inversion symmetry. In this talk, I will present two
                      complementary studies on SrRuO3 (SRO)-based heterostructures
                      that highlight different pathways to engineer interfacial
                      magnetism. In the first part, I discuss strain-driven
                      effects in SRO thin films grown on SrTiO3 (STO) and
                      STO-buffered Si substrates. Structural and magnetic
                      measurements reveal contrasting anisotropies: out-of-plane
                      for SRO/STO and in-plane for SRO/STO/Si, while transport
                      data indicate the presence of anomalous Hall effect (AHE)
                      humps linked to multiple magnetic domains rather than a
                      topological Hall effect (THE). In the second part, I focus
                      on SRO/SrIrO3 (SIO) multilayers, where the strong SOC of SIO
                      and broken inversion symmetry at the interface generate
                      Dzyaloshinskii-Moriya interaction (DMI). These multilayers
                      exhibit layer-dependent magnetization, anisotropic
                      magnetoresistance, and signatures of an additional Hall
                      contribution consistent with THE, after subtracting the AHE
                      background. Together, these results emphasize how strain and
                      SOC provide distinct routes to control interfacial magnetism
                      in SRO systems. I will conclude by outlining future
                      depth-resolved polarized neutron reflectometry (PNR) studies
                      and magnetic force microscopy (MFM) imaging to directly
                      probe the spatial magnetization profile and interfacial spin
                      textures in these heterostructures.},
